v0.19.0

• Action required: the keys changed. No action is on a bare letter, digit or
  symbol key any more, because those keys now type into the filter. The new
  defaults: alt+h help, alt+s stores, alt+f search, alt+r reload,
  alt+e edit, alt+n new issue, alt+u update, alt+a comment, delete
  close, alt+v / alt+p / alt+l the three launchers, ctrl+c quit. Move
  with the arrow keys, pgup, pgdown, home and end, and open with
  enter: h, j, k, l and o no longer move or open. ctrl+q, ?,
  1–4, ctrl+space, / and > are gone. The y / n keys of a dialog
  are unchanged. The alt+ keys need a terminal that sends alt as an escape
  prefix; on macOS turn on the Option-as-Meta setting of the terminal. esc
  and a letter that reach the app together read as that alt+ key: under tmux
  keep escape-time at 10 ms or lower, the default since tmux 3.5.
  docs/user-guide/key-bindings.md
  has the whole list.
• Action required if your config binds keys. A keybindings entry in the
  shell, board or detail context that binds a single printable character
  or space now fails startup and --check-config, with an error that names
  the key, the action and the context. Bind the action to an alt+ or ctrl+
  key, for example quit: [ctrl+q]. The modal context still takes any key.
  An entry on a key that a new default gives to another action in the same
  context also fails, for example with key "alt+n" conflicts between actions ... in shell context. Rebind one of the two. The shell actions mode_board,
  mode_docs, mode_search, mode_detail and toggle_search, the board
  action load_more and the whole search context no longer exist: an entry
  for one is ignored with a startup warning, so delete it. New actions are
  open_search in shell and move_home, move_end, page_up and
  page_down in board.
• Action required if your config binds backspace, ctrl+w, ctrl+u or
  ctrl+t. An entry in the shell or board context on one of these keys
  now fails startup and --check-config, with an error that names the key, the
  action and the context. The filter and the store search now take these keys
  first, so such a binding cannot run on those screens. Bind the action to
  another key. The detail and modal contexts still take them.
• Action required if your config binds alt+c in the shell context. alt+c
  now opens the configuration screen, and a config that already binds it to
  another shell action fails startup with key "alt+c" conflicts between actions ... in shell context. Rebind one of the two; the new action is open_config.
• Added: a configuration screen. alt+c, or the new config button on the
  menu bar, opens a screen where left and right step the theme and the
  glyph set. A change shows at once and is written to the config file, which
  keeps its comments and its layout; a missing file is created. When the file
  cannot be changed safely, nothing changes and a toast says why. esc returns
  to where you came from.
• Changed: the header. The first button on the menu bar is the name of the
  open store, in bold; it opens the store picker, as stores did. A name
  longer than 24 columns is cut to 24. On a narrow bar it is cut further, down
  to 8 columns, before a button is dropped. The text at the right of the tab
  line — the store, the view, the selected issue and Idle — is gone: each
  part repeated what the screen already shows.
• Changed: the look of the screen. On a terminal wider than 100 columns the
  app leaves blank columns at the sides, 2 on each side from 104 columns. On
  one higher than 24 rows it leaves a blank row above and below from 26 rows,
  whatever its width. The margin takes the first 4 columns over 100 and the
  first 2 rows over 24, so the app is not drawn smaller when the window grows.
  Help is a full screen and no longer a box over the screen: the keys stand in
  sections in one column, the keys of Detail, of a dialog and of the
  configuration screen included, alt+h or esc closes it, and enter no
  longer does. A description too long for the screen goes on in its column on
  the next line, and a help taller than the screen reads … (N earlier) on its
  first row and … (N more) on its last. The configuration screen has the same
  chrome: a title line, a rule, one blue line and a second rule. On the
  configuration screen the blue line names the config file a change is written
  to. A menu-bar button has a space on each side, and the button or the tab
  under the pointer is lit over that whole cell; a click anywhere on it counts.
  A button's label is the text colour, and the rule under the bar starts under
  the first label. In the key legend the key is now the dim part and what it
  does the bright part, the hints are joined by •, the line starts one column
  in, and it ends in … when hints are left off. The bar is wider, so a narrow
  terminal drops the version and the last buttons sooner. The band on the row
  under the pointer is now the shade between the background and the selected
  row: lighter than the background on a dark theme, darker on
  catppuccin-latte. A 256-colour terminal draws that band in a grey. A
  16-colour terminal has no shade for it: the row under the pointer is not
  marked there, a tab changes its text colour and a button's label turns bold.
• Fixed: a directory with a line break or a tab in its name broke the store
  picker. The path drew on two lines, so a click landed one row off. A store
  name and a path now draw on one line, without format characters such as a
  right-to-left override. The error of a failed store listing does too: a
  registry file with a value of the wrong type gave an error of two or more
  lines. The same holds for the create-store form, every toast and the error
  of a board column or of the detail view: a directory name with an escape
  sequence in it reached the terminal from the create-store form. A format
  character that shapes nothing, such as a right-to-left override or a soft
  hyphen, is dropped; a joiner in an emoji or a script stays. A long error on
  the detail view wraps, and a toast draws at most 6 lines, the last a …
  when it cut the message.
• Added: type to filter. On the Board and Docs tabs every key you type goes
  into a filter on the line above the columns. A row stays when every word of
  the filter is in its title or its ID. The matched text is marked and each
  column header reads N of M, the matching rows of the loaded rows.
  backspace, ctrl+w and ctrl+u edit the filter and esc clears it. The
  filter stays through a tab switch, a detail round trip and a reload.
• Changed: search is no longer a tab. alt+f, or the new search button
  on the menu bar, opens the store search from a tab or from the detail. It is
  one list of results and searches as you type: a search runs 150 ms after the
  last key, and enter pressed inside that time opens the result of what you
  typed. There is no enter to run the query, no preview pane and no pane
  focus. ctrl+t still switches between open issues and all issues. A search
  shows at most 100 results and the header reads 100 of M when the store
  holds more. esc clears the query and then returns to where you opened the
  search; from a result's detail esc returns to the results. The view tabs
  are Board and Docs.
• Changed: the Done column loads the next page of closed issues only by itself,
  when the selection comes near the end of the loaded rows. The > key that
  loaded a page on demand is removed.
• Added: pgup, pgdown, home and end move the selection on the Board, the
  Docs tab, the store search and the store picker.
• Changed: when the terminal is too narrow for all board columns, the columns
  stay in place until the focus leaves them, and then move only as far as
  needed. A click or left/right on a column already drawn no longer shifts the
  board. The wheel now scrolls the column under the pointer and focuses it.
• Fixed: one central store directory that cannot be read no longer empties the
  store picker. That store is listed as broken, and enter on it shows the
  reason on a second toast line.
• Fixed: one central store directory that cannot be read no longer stops the
  app from starting elsewhere. Before, taskmgr-ui exited with failed to open task-manager store for ... in every directory that has no local .tasks
  store. It now opens the store of that directory, or the store picker when the
  directory has none. Only a start in the project of the unreadable store, or
  with --store-name on it, still fails.
• Fixed: the error toast of a refused write said the reason two times. A write
  that a hook refuses, or that the store finds not valid, names it one time.
• Fixed: the result of a write, an edit or a launcher that came back while help
  or a dialog was open was lost, and no toast reported it. The toast now shows.
• Fixed: when the detail of an issue failed to load, the toast Failed to load selected issue details came back on each change of the store and each timed
  refresh. It now shows one time for an issue, and again when you reload.
• Fixed: a refresh you did not ask for moved the cursor to another issue in the
  Done column when other closes had pushed the selected issue below the rows
  already loaded. The refresh now loads up to 3 more pages of Done to find the
  issue again, and the cursor returns to it. When the issue is not in those
  pages, the cursor stays on its row as before.
