Last Step Undo CKAN

Last Step Undo Last Step Undo adds a blue curved-arrow Undo button to the VAB and SPH in Kerbal Space Program 1.

Clicking the button uses KSP’s stock Ctrl+Z part-undo function, allowing you to reverse your most recent rocket-building edit. The mod focuses entirely on craft parts—camera movements are not added to the undo history.

Features Blue one-click Undo button in the editor Ctrl+Z keyboard support Works in both the VAB and SPH Undoes rocket-part edits Does not record camera movement No ModuleManager or Harmony dependency Compatibility Kerbal Space Program 1.12.5 Windows 64-bit Not compatible with Kerbal Space Program 2 Installation Download and extract the ZIP. Copy the included GameData folder into your main Kerbal Space Program folder. Allow Windows to merge the folders if asked. Start KSP and enter the VAB or SPH. Look for the blue curved-arrow button near the top editor toolbar. The installed DLL should be located at:

Kerbal Space Program\GameData\LastStepUndo\Plugins\LastStepUndo.dll

Uninstallation Delete:

Kerbal Space Program\GameData\LastStepUndo

Please continue saving important craft normally because KSP’s stock undo system can have occasional edge cases involving held or duplicated parts.
