Patterpad 0.12.0

Added

• Back and forward. A quiet ← → pair at the top left retraces the documents you have visited,
  greyed when there is nowhere to go, with View ▸ Back / Forward behind it (⌃⌘← / ⌃⌘→ on a Mac,
  Alt+arrows elsewhere). It is the other axis from the navigator: the navigator climbs, Back
  retraces. Scenes, the Properties page and the Project Overview are all places, and moving the
  caret around a scene is not a journey, so a Back into a scene lands where you left it.

• Properties have their own page. @patter properties are the story's working vocabulary, and
  they were living in a tab of the Project Settings dialog, which treated them as configuration.
  There is now a Properties row at the top of the navigator, above the scenes, carrying a count
  of what the project declares; it opens a page in the editor's column, with the navigator still
  beside it. Edits save as they settle, the way a document does, instead of on closing a dialog.
  World Properties stay in Settings, beside the coverage drivers: that half really is configuration,
  the contract with your game, and the page links across to it. If you were last on the page when
  you quit, that is where the project reopens. (from-storylets/property-visibility.)

• A property chip says what it is for. Hovering a property in any condition or effect shows the
  purpose written on its declaration, and, for a Quality, its ladder of stages. Nothing to fill in
  that you have not already: it is the Purpose field in Settings ▸ Properties.

• Right-click a property: Go to definition, Find usages. Go to definition opens where it is
  declared (@patter in Settings ▸ Properties, a scene property in that scene's editor, @world in
  Settings ▸ World Properties); Find usages opens the search window's property mode, which lists
  every read and write with its location. On every property chip, including the target of an effect
  and the read-only rows in the inspector. (from-storylets/property-visibility; expr-editor 0.14.1,
  which also carries the fix for a preview's target chip having neither.)

Changed

• One row of chrome, not two. On macOS Patterpad's own topbar is now the window's title bar: the
  native strip above it carried nothing but a title the bar already showed, so it is gone and you get
  the row back. Off macOS the window keeps its native frame and the bar sits beneath it as before.
  In Writing View the bar no longer collapses; it fades back instead, and firms up when you point at
  it - collapsing it would leave the traffic lights floating over your prose.

Fixed

• Move and delete buttons in the property lists centre their glyphs (app-shell 0.33.1).
