Yup, I cursed a couple of times when this happened to me too. Now hitting “Save” button very often. I would love an auto-save feature IF it saved under different names everytime (sometimes I am just trying things, and hitting “save” is my way to commit the change). A rolling auto-save buffer with the latest 5 auto-saved versions would be great.
What I would like even more is the ability to debug this kind of crashes myself somehow (wink wink @robgrz )
