I'd like to add "autosave Snapshot on exit" and rework the exit logic

[cormacj]

I'm considering adding a parameter and an option for auto-saving a snapshot on exit (if enabled or called).

The reasoning here is that sometimes I accidentally exit out without having made a disc change (F11/paste is really close to F10/Quit), so the program just exits. The autosave on exit would just write/overwrite a named snapshot file that contained the last open state if no disc changes were made.

I'm also considering a change to the exit logic, where instead of asking "Unsaved changes. Do you really want to quit? Yes/No" it would ask "Unsaved changes. Do you really want to quit? Yes/No/Save" and the save option would open the save dialog and pre-fill the last opened filename as a default, rather than the current "F1/Load-Save/Save/Specify a filename" path thats kind of clunky.

Any thoughts or concerns with me making these changes?

That's a good idea. The snapshot could be dated, configuration could rely on the presence of a snapshot_autosave_dir in the configuration. What do you think?

Caprice GUI framework is not the best and this may a bit hard to do, but if you find a clean way to do it, that would definitely make users life simpler (though I'm not sure how many users actually write something on disk anyway :-) ).
