super-prototyping 1.6.0

2026-09-23. The app is the only install. It opens on a home page with a tab
per project, keeps one agent conversation across them, and updates itself.

• The app is the only install. There is no plugin to add any more. On
  macOS and Windows every launch puts sp, refkit and artgen on your PATH
  and links the skills into Claude Code, Codex, Hermes and Factory, so updating
  the app updates all of them. sp uninstall takes them back out. If you
  installed the plugin, remove it with /plugin uninstall super-prototyping
  (or your product's equivalent). On macOS, also remove the old toolkit with
  uv tool uninstall super-prototyping-tools before opening the new app (or
  open it again afterwards); on Windows the app replaces it.
  An agent with only the skills installs the app with the prototype-canvas
  skill's scripts/install.sh, or install.ps1 on Windows.

• A canvas has its own background colour. Right-click the canvas for
  Background (dark grey, black, light grey, white or a colour of your own), or
  use the swatch at the end of the canvas strip. The colour is saved in the
  canvas's layout.json, so it travels with the folder. The default ground is
  now dark grey, and Start here's is black.

• Boards no longer carry a status. The Exploring, Outdated and Live badge
  is gone from the inspector, and no bar is drawn above a board. A status
  left in a layout.json is ignored.

• Drag a box around boards to add them all to the chat. A + at the
  selection's corner adds every board and picture in it at once. The canvas
  keeps only its select and comment tools, so a stray key no longer drops you
  into a drawing tool.

• The chat stays where you scrolled. Reading back no longer jumps to the
  bottom when the agent writes more. A ↓ button takes you to the latest, and
  sending a message follows it again.

• A file the agent links in the chat opens. Its links to pages it made in
  the project used to do nothing. They open in a new window now, with the
  page's own styles and images, and only files inside the project are served.

• A past conversation shows its turns again after an update. Opening one
  from History used to show an empty panel once the app had restarted, which
  every update does. Each turn is now saved as it happens, pictures included,
  so the conversation reads as it did. Turns from before this version were
  never saved and stay blank; the agent still remembers them.

• A new board lands in its place and glows. When the agent adds a board
  in the middle of a row, the boards after it move over to make room instead
  of the new one landing on top of them, and one that is removed or renamed
  leaves no copy behind. No force refresh needed, and the view stays where you
  were looking. Whatever just arrived keeps a blue ring until you point
  at it, through the reloads the agent's next boards cause.

• A board added to the chat shows up at once. Its tile and its number
  appear the moment you press + or paste its link, shimmering while the board
  is drawn, and the picture fills in when it is ready. Send waits for it. A
  board that cannot be drawn turns amber; press its + again to retry. Several
  boards added together are drawn side by side, four at a time, so three take
  about as long as one.

• Copy a link to anything on the canvas. Right-click a board, a picture or
  a card and pick Copy link, or select it and press ⌘C (Ctrl+C): it opens
  the canvas on that thing. With several selected, it copies one link a line. Paste them into the agent's box and they
  become those things' chips, the same ones their + adds. The menu lost Clone this canvas, Edit and Arrange: a board is
  laid out from its folder, so none of them stuck.

• The app opens on a home page. The desktop app opens on every project you
  have, with the examples below. The page is no project's, so the app works
  with none: open an example, or close every tab, and nothing is made or
  reopened for you. Each card shows the
  project's cover.
  Open one, or start a new project from the same page. With none yet, a dashed
  card sits under Projects where your first one will be, and a click on it
  starts that project. The Home button on the canvas's top bar goes back to it.

• A project has a cover. Its card on the home page shows its first
  canvas's first screen, captured the way the canvas draws it, until you pick
  another: right-click a board or an image on the canvas and choose Set as
  cover, or right-click an element on a board the inspector has open to keep
  that element in view. Setting a new one replaces the last, and Reset cover on
  the card's right-click menu goes back to the first canvas.

• Right-click a card on the home page to open it, copy its link, show its
  folder in Finder or Explorer, or move it to the Trash (Delete, on Windows),
  where you can put it back. That asks first, with the folder's path in full.
  An example has only Open and Copy link.

• Right-click a tab to copy its link, reload the canvas in front, show a
  project's folder, or close it, the other tabs, or all of them. Home has Copy
  link and Reload. The browser's own right-click menu no longer shows over the
  app, except in a text field, where it keeps Paste and spelling.

• The first launch asks one question, over the app. It no longer asks for
  a project before you see anything. It opens on the home page, with no project
  made for you, and asks over it which agent you will work with. Skip it and it
  asks again next launch. It comes back once after a major update.

• A tab is a project. The bar across the top holds one tab per project you
  have open, examples included, and each comes back on the canvas you left it
  on. The + at the end of the bar starts a new project. Open another from the
  home page.

• A project's canvases are tabs under its tab. A second row under the bar
  lists the project's canvases, the one in front underlined. Its + asks the
  agent for another: the panel comes out with the message begun, the box rings
  once, and the cursor waits at the end of it for you to say what the canvas is
  of. Export to Figma moved from the top bar to the Figma mark at the row's far
  end, and in the desktop app it opens in your browser, where the
  html.to.design extension can capture it. The top bar's Brand kit button is
  gone.

• One agent for the whole app. The agent panel stays down the left on the
  home page and on every project, with the same conversation. The button at the
  start of the bar shows and hides it, and shows the mark of Claude Code or
  Codex, whichever the next message goes to. Right-click it to switch.

• The agent remembers the conversation. Each message carries on from the
  ones before it, until New session starts another. It works on the home page
  with no project open, and on whichever project is in front when you send, so
  one conversation can move between projects. History lists your sessions, with
  the projects each worked on, and picking one carries it on. Switching between
  Claude Code and Codex starts a new session.

• The agent has a folder of its own, and projects get no skills. It runs in
  .workspaces/<session> under the projects folder, where it gets the plugin's
  skills, and writes boards into the project in front. Making or opening a
  project no longer copies skills into it, and the toast that said so is gone.
  Copies an earlier version put in a project are left alone and no longer
  updated; delete them if you like. sp paths names the folder, and sp clean
  leaves it alone. Claude Code needs 2.1.275 or later.

• Switching tabs keeps what you typed. The bar and the agent panel belong
  to the window, and a project's canvas loads beside them, so switching
  projects, going home, opening a project, or a board the agent writes reloads
  only the canvas. A half-typed message, its pictures and the run being
  followed stay as they were, with no flash.

• One server for every project. The app starts its canvas server once and
  serves every project from it, so opening another project or switching tabs no
  longer restarts anything.

• sp start is that same server. It serves every project under
  ~/Documents/Super Prototyping at /p/<name>/, as the app does, and the
  project it was given beside them, which is where its address goes. The
  plugin's examples show beside each project's boards. New project and Open
  folder are the server's own, so the app and a browser tab get the same ones.
  --canvases is gone, and the server no longer reads
  PROTOTYPING_CANVASES_DIR. A project's boards are its canvases folder, and
  PROTOTYPING_PROJECTS_DIR moves the projects folder.

• A project's boards moved up a level. They are in <project>/canvases
  now, not <project>/mockups/canvases. The first time sp start, the app or
  a browser tab opens a project that still has the old folder, it moves the
  folder, and an emptied mockups goes with it. A project that has both is
  left as it is, for you to merge.

• Start here is the first example. It is the first card under Examples on
  the home page, and opens on a tab of its own, labelled Start here, like every
  other example. A project with no canvas yet
  still opens on the same page, under its own name. Close that tab, or every
  tab, and the canvas goes back to the home page.

• The app updates itself. On launch it looks for a newer release, downloads
  it in the background, and then asks once: Restart Now, or Later, which
  installs it when you quit. Only what changed is downloaded, so the example
  boards are not fetched again: a few MB on Windows and about 50 MB on macOS,
  where the first update after a dmg install is still the whole app. Offline,
  it says nothing. A Homebrew install updates this way too. Installs of v1.5.3 and
  earlier have no updater, so they need one last manual update:
  brew upgrade --cask super-prototyping, or the new installer on Windows.

• The app says which version it is. The first launch's welcome shows it
  at its foot. Click it to check for an update there and then: it answers Up to
  date, that a newer version is available, which then downloads and asks as
  usual, or Could not check.

• The online canvas has moved to
  prototyping.rescience.com/demo.
  The domain itself is now a page about Super Prototyping, with the downloads
  on it. Links to a board written before the move still open it.
