Well, they already have a “auto-backup” feature, it just doesn’t target config files, only files you open in the editor and when you make changes to that file and haven’t closed it.
I made my own program to just copy files, but I’m not ready to look at doing something that checks every possible setting for a comparison against original or recently changed config files that may have had only minor changes. I think that’s why something like this hasn’t been done yet. So many settings, AND between versions, the menu and the options may change as well, so if someone wrote such a program/plugin/feature, it would have to be constantly updated for when the Notepad++ program changes, as well.
