Global Pane Switcher. Tap ⌘ twice (or View → Show Pane Switcher) to open a centered overlay listing every running pane across all your spaces, numbered 1–9 so you jump straight to one with a single key. It opens on the pane you're already in, works in both the Normal and Spaces layouts, and lets you hop to a pane in another space without first switching spaces. Arrow keys, Return, and click work too.
The window behind the switcher ripples with a Metal splash as the card drops in, toolbar included. The whole effect is skipped when the system Reduce Motion setting is on.
Per-space activity on the Spaces proxy-icon bar. A space holding an agent that needs your input pulses orange on its icon, one that has finished its turn pulses green, so a space you aren't looking at can still get your attention.

Fixed a crash that could occur when a section filter hid the project that owned the selected pane.
