It would be nice if, whenever a user creates a new selection mask, there would also be an on-canvas bar with common selection-related actions, somewhere below the selection mask. Like the assistants bar, it should probably only be shown when selection tools are activated. Ideally, it would also be configurable like a typical toolbar, and able to be disabled through the View or Settings menu.
The main advantage of having this bar is that common selection actions become readily available and discoverable, so that users don’t have to look through menus or use shortcuts/right-click.
A mockup of one theoretical configuration, using the existing assistants bar as a base:
(Shown from left-to-right: Move handle for the Selection Mask, Invert Selection Mask, Crop to Selection, Fill Selection with Foreground Color, Copy (or Cut?) Selected Content to new Layer, Transform Selected Content, Deselect Selection, and a move handle for the bar itself.)
For reference, CSP refers to this as the selection launcher. More information can be found in CLIP STUDIO PAINT Instruction manual - Selection Launcher
