For example, the "autosave" can be pretty handy. You enter some text into a tab, close sublime. You have no annoying dialogs asking you to save the file etc and the comtent is saved so that it is available in the same state when you reopen.
If not for the save your ass by not losing work bit, I like it for not being annoying.
I actually use "autosave" as a temporary clipboard. When I need to keep something over multiple days but don't need it forever (i.e. big, hairy command strings) then I just open a new tab and paste it in. That way I can continue to copy/paste the command whenever I need it and as long as I don't close that tab I'm good to go. :)
