Revert undoes one specific change wherever it sits in the history. Unlike a plain Undo, which only peels back the most recent change, Revert lets you reach into the list and cancel a single entry, leaving everything that came after it in place. This is what makes history safe to use when several people are editing at once.
Surgical, not a time machine
Reverting is deliberately precise. When you revert an entry, livediagram restores the before state of just the elements that change touched: elements it had added are removed again, elements it had deleted come back, and elements it had edited return to how they were. Nothing else on the tab is affected.
That precision is the point. Reverting your colour change from earlier does not throw away the boxes a teammate added afterwards, because those were separate changes with their own entries. There is no "rewind the whole tab to this moment", only the targeted cancellation of one change.
How to revert
Open the Activity Panel and find the change you want to undo. Remember the panel is scoped to the active tab, so switch to the tab the change happened on.
The affected elements snap back to their previous state, and the entry is removed from the list.
A revert is treated as cancelling the original change rather than as a new event of its own, so the panel stays compact instead of filling up with paired "reverted" rows.
Revert versus Undo
Both have their place:
- Undo / Redo (in the panel header) step backwards and forwards through your most recent changes in order. Reach for these when you want to take back what you just did.
- Revert targets one entry anywhere in the list. Reach for this when the change you want gone is buried under later, unrelated work, especially work that is not yours.
If you only need to take back your last action, Undo (Ctrl+Z) is quicker. Save Revert for when the change you want gone is no longer the most recent one.
