hey there - first of all, I'm using Lay themes for a while now and its absolutely amazing!
BUT
It happened multiple times already that i spent 20-30 minutes on a row with various elements, i change the tabs to google something, come back, accidentally pressing on the little X next to the row. And then its gone. Just like that.
I know as a designer you should always save every little step. But I just lost a footer element I was working on for like 20-30 mins in a matter of second.. Thats pretty frustrating.
