Undo - Ctrl+Z for RimWorld
Misplaced a wall? Mined the wrong column? Accidentally cancelled your entire blueprint? Just Ctrl+Z.
This mod adds proper undo/redo to RimWorld. Actions are grouped by drag - one Ctrl+Z reverses your entire selection, not each cell individually.
Keybindings
- Ctrl+Z (or Cmd+Z on Mac) - Undo
- Ctrl+Y or Ctrl+Shift+Z - Redo
What Can Be Undone
- Blueprint placement - walls, furniture, floors, power conduits, everything
- Mine designations - never accidentally collapse a roof again
- Cut plant designations
- Harvest designations
- Hunt designations
- Haul designations
- Deconstruct designations
- Cancels
- Zone creation and deletion - stockpiles, growing zones, etc.
How It Works
Only designations and blueprints (orders you give) can be undone. Once a pawn physically builds a wall or mines a tile, that cannot be reversed - this mod respects the simulation.
The undo stack is per-map and clears on save/load. Drag-select operations are batched into a single undo step, so one Ctrl+Z undoes the whole drag.

Requirements
Known Limitations

- Forbid/unforbid is not tracked (trivially reversible by the player)
