Mockup shows "PiP" as the 6th grid cell and a toolbar button. What does PiP do that snap-6 doesn't? Always-on-top mini overlay anchored bottom-right (ignores work-area)? Same as snap-6 (just rebrand)? Picture-in-picture floating that follows the cursor?
Toolbar has a dedicated snap-right (↦). Snap to slot 3 (top-right), slot 6 (bottom-right), or explicit half-screen-right?
Toggle the existing 10s auto-fade on/off, or trigger an immediate fade now?
Mockup shows "Shift+6" baked into the titlebar. Read from the actual --hotkey arg, or hardcode the label?
Cream → slate panel, Courier → system sans-serif, recolor traffic dots, bump corner radius.
Add teal PiP badge (when slot==6 or PiP active), hotkey label on far right. Drop or relocate the file counter.
