Adds always-accessible Undo and Redo buttons to the 3D Viewport sidebar (N-panel), neatly stacked vertically in a dedicated "Undo / Redo" tab.
Espacially useful for using an ipad with Sidecar for Blender since there is no undo shortcut.
Works seamlessly across Object, Edit, Sculpt, Draw, and other modes. Perfect for tablet users, stylus workflows, or artists who prefer quick-access UI over hotkeys.
