My DAW has a nice feature: "Save as new version" which avoids using "Save as..." and change the filename by hand.
It works like:
Original: "filename.xyz"
First "Save as new version": "filename-01.xyz"
Second: "filename-02.xyz"
Third: "filename-03.xyz"
etc. etc.
The good thing is there's no popup needed. And the new file becomes the actual (opened) file of course.
Save as new version
Re: Save as new version
Hmm I guess so, but that's a lot like the auto-backup feature that's already implemented.
