LAST STEP UNDO for Kerbal Space Program 1

The compiled LastStepUndo.dll belongs in:
  Kerbal Space Program/GameData/LastStepUndo/Plugins/

The curved-arrow button appears at the upper-left of the VAB and SPH.
Each click reverses exactly one recorded step. Camera moves and zooms are
separate steps from rocket edits.

This early build is intended for KSP 1.12.5 and must be tested against your
installed copy of KSP before relying on it with an important craft. Save the
craft normally as an additional safety measure.
