Chord 0.3.0

Arc's archive, Peek and downloads wired to Chromium, imports from other browsers, a
welcome on first launch, and media controls in the sidebar.

Added

• A welcome on first launch, on one glass panel: import from Arc or another browser,
  make Chord the default browser, and the shortcuts to know.
• Import from Google Chrome, Brave, Microsoft Edge, Vivaldi, Chromium and Safari
  (File › Import from Another Browser…, or Settings › General): each profile becomes a
  Space with its bookmarks bar as pinned tabs, and its logins, passwords, history and
  extensions come into that Space's profile. Safari gives its bookmarks and history
  once Chord has Full Disk Access.
• The archive, like Arc's: tabs closed with ⌘W, and today's tabs left unused for 12
  hours, go to the archive (⌥⌘A, or the box at the bottom of the sidebar), searchable,
  where a click opens them again. Settings › General › Archive today's tabs: 12 hours,
  24 hours, 7 days, 30 days or never. Archived tabs also show in the command bar.
• Media controls in the sidebar, like Arc's mini player: a tab playing sound or video
  out of sight shows above the Spaces, with play / pause and mute, and a click goes
  back to it.
• Each Space can have an emoji, shown in place of its dot (the Space's menu › Icon, or
  Settings › Spaces).
• A cheat sheet of the main shortcuts at the bottom of the command bar, as remapped in
  the settings.
• ⇧-click on a link opens it in a Peek, and a link leaving the site of a pinned tab or
  a favorite opens in a Peek too, so the tab stays on its page.
• Downloads appear in Chord's downloads panel as they run, saved to Downloads without
  asking where; a file the browser warns about waits there for "Keep".
• A video in full screen fills the window alone: no sidebar, toolbar or margins.

Changed

• ⌘W in Chromium's own windows (developer tools in their own window, a site's popup)
  closes them: Chord's menu bar is the only one.
• VoiceOver reads the sidebar, the command bar and the welcome better: one element per
  row or tile, the current Space told apart, the result picked with the arrows read
  aloud, no more site initials read on their own.

Fixed

• Pages show their true colors: they no longer blend with the window's glass, which
  washed them out (grey blacks, faded tints).
• Turning edgeless mode on or off no longer leaves the bottom of the page empty until
  a reload.
