When AutoSave is toggled on, any changes made in the librarian left bank view will be automatically saved. This is a dangerous function, but as per request, we included this feature.
JP-80×0 Editor User Manual – AutoSave Librarian Changes
NOTE: Be aware that there is NO UNDO function, so you cannot revert to the previous state if you make a mistake. We would advise to make a copy of the original bank (if needed) before making changes to the bank with autosave on. Defaults to off state.
