Shout out to Paint.net! Great software, but it’s almost 20 years old and still doesn’t have an Autosave feature. The forums are full of people begging for this feature for years and they still haven’t added one. Their response is the classic “you should save more often.”
I’ve started using LibreOffice and it likes to crash on my PC pretty regularly. It’s kind of a pain to have to re-open my document every half hour, but it never fails to recover exactly where I left off.
Anyway. Autosave. Good feature.
Speaking of, PDN has the Edit History, which is a really useful feature too! Why can’t that be saved to a supplementary file so I can keep my history when I close and re-open my image? That would be pretty slick.
I guess such sidecar files are annoying for the gros of users. A configurable option for it might be an idea though.
