Give us the option to either 1/ turn off autosave (temporarily) or
2/ set the time intervals for when it does autosave (say max of 30 mins)
My reason for this is that often (in fact almost always) I play around with the layout/styles when I get near to the finished design and ready for exporting, sometimes more often than not this approach usually takes longer than the intervals between autosaves) but it may be that in the end I don't actually want to keep the changes that I have been playing with.
unless it is my app and there is something else wrong, what happens at the moment is if I decide NOT to keep the changes to the design, then I should be able to close the app and discard any changes I made, but this doesn't happen, because when I close it simply closes, no option to save or discard, then upon re-opening it opens with what looks like the deign which was saved with the last autosave. I have gotten around this by actually doing a back-up to the project before trying any design style changes, but is is a bit of a pain in the rear to keep remembering to do that, and especially with the number of different projects on the go every day.
Just a suggestion
