Opening it
Click History in the assistant header. Review in the save bar opens the same panel, on your unsaved changes.What you see
At the top sits Draft — unsaved changes: what you have edited but not saved yet. Under it, Version 1, Version 2 and so on, newest first, each showing the settings that changed in that save and what they were before. Show older versions loads the rest.Reverting
Each line has its own Revert. Reverting puts that one value back into your draft — it does not touch anything else, and it does not save by itself. Look at the change, then press Save assistant to keep it.Because a revert lands in the draft, you can revert several lines, look at them together in the save
bar, and save once.
