Still I agree that autosave should come standard. I'll take waiting an extra few seconds over losing 30 minutes of work any day. Especially annoying is the fact that when you relaunch the software after it crashes, this peppy little message comes up urging you to check out new Reallusion content, like nothing happened. :)
If you decide to implement this feature, Reallusion, please make it optional. As projects get bigger, they can take a 'considerable' time to save, and an autosave could become extremely irritating in those circumstances if it couldn't be turned off. Thanks!
