Undo, Redo and removal
Use Studio history for the changes authored by the plugin.
Atomic authoring
Use Studio Undo and Redo for setting changes, completed drags and Cancel. One drag is one history step. Applying a behavior creates its own step, so you can undo the save without losing the editable draft.
Save your place to keep unfinished work. A draft can be restored if its saved behavior has not changed. Use Apply when you are ready to make the interaction available to players.
Remove behavior
Load the assembly and choose Moving parts > Remove saved behavior. Geometry remains. Shared scripts remain because other mechanisms may still use them. Remove shared code manually only after confirming no mechanisms depend on it.
