While I usually remember to save fairly often, I do forget every now and then. As fate would have it, today I forgot to save for about 2 hours and then my program crashed and I lost all the work I did, with no way of recovering it. What is more irritating, is that when you are working on a lot of diagrams that are fairly complicated, it often happens that you don't only lose the obvious additions and expansions to your diagrams, but also all the small changes made to existing diagrams. This is extremely frustrating, as remembering every little thing you did is nearly impossible. I have noticed that there is no autosave function on Bizagi, even though people on this forum have been asking for it for a number of years. Is it something you are looking into?
