• Line up the ⌥ stack. Settings ▸ UI ▸ Recent Boxes has a new Align
  choice: Start, Center or End. Start lines the recent boxes up on the
  side their lines begin, the left for most languages and the right for
  Arabic and Hebrew, so short and long boxes read down one edge. End lines
  them up on the other side, and Center keeps them centered on the live
  box, as before. Start is the new default.
• Changes show at once. Changing Align or Text in Settings while ⌥
  holds the stack up redraws it on the spot, and a new alignment slides
  the boxes across rather than jumping.
• The search stays centered. The ⌥F search pill stays in the middle
  of the live box whichever side the boxes take.
