Customizable Quick Actions bar
Drag-reorder the twelve icons at the bottom of the viewfinder.
Where to find it
Settings Quick actions bar (long-press a row in the editor to drag)
Summary
The viewfinder always shows two rows of six icons. Open Settings > Quick actions bar to drag any icon into the order you like; the change persists across reboots and profile switches. The bar's twelve icons stay visible at all times so power-user shortcuts never disappear into a tray.
Detail
How it works
What the bar holds
Two rows of six icons sit below the live preview. The defaults are: Layers, Filter, Black and White, Histogram, Metering Mode, Composition Grid on row one, and Tools, Framing, Shot Log, What should I do, Flip Orientation, Settings on row two. All twelve icons stay visible at all times — nothing is ever hidden in an overflow tray.
How to reorder
Open Settings, scroll to Quick actions bar, and tap. The editor opens full-screen showing the current order with a small drag handle on each row. Long-press a row and drag it to the position you want; release. The viewfinder bar updates the next time it draws. Tap Reset to default to restore the original layout.
Per-profile persistence
Your order is saved on the active profile (Profile.quickActionsOrderCsv) and reloads on cold start, reboot, and full app close-reopen. Switch profiles and you get whatever order that profile was saved with — a documentary profile can lead with Histogram and Multi-Spot while a portrait profile can lead with Filter and Framing.
Why two rows of six
Twelve slots fit comfortably below a 4:3 preview on a portrait phone without forcing the touch targets below the minimum 48 dp Material guideline. Hiding rarely-used icons in a More tray loses the muscle memory that makes the viewfinder fast; you might tap an icon you barely use once a month, but when you need it you want it where it always lives.
