Workspace and canvas
Canvas navigation, toolbar placement, and tool settings.

Panels and toolbars
The workspace contains the canvas, toolbars, brush list, color controls, and Layers panel. A tool’s settings contain parameters for the active tool, such as brush size and opacity.
Canvas view
Pan, zoom, rotate, and mirror the canvas view. These operations change the display, not the document’s pixels. Fit the canvas to the window or reset the view to its default orientation.
Workspace layout
Move toolbars, show or hide panels, and change which controls a toolbar contains. Open a toolbar or tool’s settings to configure it. Reset the layout to restore the default arrangement.
