Terminal/Workroom quick switcher #132

A keyboard shortcut (opt+tab) to see and switch between open workrooms, and one (ctrl+tab) to see and switch open detail panes (terminals, diffs, files, etc.), in the same style and behaviour as the MacOS app switcher (cmd+tab).

It should exhibit the same behaviour as the MacOS native app switcher...

• Quick tap of shortcut should switch to next
• Tap and hold of primary key in the shortcut (opt or ctrl) should show the open workrooms or detail panes in a centred horizontal rail of screenshots and accompanying labels.
  • Tapping left and right while the rail is shown should move left or right along the rail.
  • Support mouse hover and click of any item in the rail
• Should show count label of any notifications on each item in the rail.
