Thanks! Lost my work twice in the past few days, power cut and then a crash today :(
I find it absurd that GIMP does not have this built in yet, the bug report requesting auto-save is still open with comments from 15 years ago!

Does this script crash for anyone else? When I use it says it may have messed up the internal state of Gimp because the script has crashed

So.. this plug-in DOES go in the /home/username/.gimp-2.8/plug-ins/ folder

You do not have to jump through hoops downloading obscure packages to figure out how to register it in Gimp.
You do not have to do a bunch of top secret command crap in terminal.
You do not have to hack it in to the system directory or install a system Python version.
Once you have it in the proper folder, go to the file properties for the script and make it executable.
That is all.
God alone knows why.

If you still don't see it on the FIle menu the next time you open Gimp, close Gimp, go to the /home/username/.gimp-2.8/ folder and delete the pluginrc file. open Gimp again, and it will rediscover all of the add-ons.

Ta-Da!

Extracted your plugin into /home/username/.gimp-2.10/plug-ins/ folder. Made it executable. Opened Gimp but the entry did not show up under File. So I deleted /home/username/.gimp-2.10/pluginrc. Restarted Gimp but it still didn't show up! I wonder if you could help me.
