Automatically save ALL unsaved projects regardless of XCF
I love making a quick edit, but there is nothing worse than a crash after spending 15 minutes on a throwaway photoshop. Make GIMP automatically save temp files for all edits, and if an XCF is saved, then store the backups for that in its appropriate place from there on.
Your software crashes for different reasons, so no need to pinpoint the crash, just have it save all projects immediately, no need for an XCF.
