Me again. I lost an entire days work again, (yes, my fault for not saving), and I would REALLY REALLY REALLY REALLY love an autosave. Every audio and video software I use has one. And other creative programs just automatically keep the most recent version of the project as the new one.
The fact that I can continue to use Mad Mapper for hours on end, and if *I* don't hit save I could lose the work, is really really frustrating. Please add autosave!
