- PlayerPanel now leaves an 8px bottom margin so the transport row
isn't flush against the tab's edge.
- Frame-step buttons read '⏮ Frame' / 'Frame ⏭' instead of
'⏮ Frame (,)' / 'Frame ⏭ (.)' -- the shortcuts still work, just not
spelled out on the buttons.
- Detect Next Clap is now a button in the Sync markers panel next to
Detect All Claps (still also in the Tools menu), kept in sync with
its menu action's enabled state the same way Detect All Claps was.
