I know that i could be called "lazy", but from time to time i start a Substance Project without saving it, and then i get so sucked by the rush of focus on it that i constantly forget about saving the project like after 1h of working. And, not rarely, my Substance Designer eventually crash (usually when i keep switching back and forward from OGL and iRay render) and bam. Everything is gone. Since the Autosave feature can't help me if i never saved the project.
Would be very nice if as soon we start a project, a temporary "untitled_##.sbs could be saved inside documents or any default substance folder, so when this happen we could save our ideas from there and save it properly as a project.
Sometimes i don't save something because i am just sketching and testing thing, but then it turns out in something cool, or a great finding, and BAM, lost everything...
I KNOW, it's my fault, but i will let that as a suggestion anyway.

Would be very kind for chaotic artists (like me).
