History, undo, and redo
Inspect up to 100 personal content actions and reverse your own available steps.
Open View → History to see personal content changes newest first. Outside a text field, use Cmd/Ctrl+Z to undo and Cmd/Ctrl+Shift+Z to redo. A focused input or rich-text editor keeps its own local typing history; its committed edit becomes a server History action when the edit boundary closes.
Each row names the action, actor, time, applied or undone position, and whether it remains available. Undo and redo rerun permissions and conflict checks. If another change makes the exact inverse unsafe, the step stays visible as blocked or invalidated with a reason instead of overwriting newer work.
A person can reverse only their own actions. A GM may select a player to inspect that player's list, but receives no cross-user undo or redo control. Use Forget unavailable step to remove a blocked row from your own stack.
History keeps at most 100 actions per person within per-user and per-world storage bounds and survives reconnects and world restarts. Chat, rolls, membership, policy changes, mod lifecycle, active-scene changes, content-pack orchestration, and explored-fog reset are outside personal content History. Permanent operations say so before they run.
