I just spent 10 minutes preparing a question and made the mistake of double clicking on an image hoping an edit tool might come up to crop it. It just loaded the picture file raw into the widow so I went and did cropping in Finder Markup tool and came back. Lost the tab I was working in for a while and then closed the image tab by mistake which was actually the page I had spent 10-20 minutes preparing a draft in. I clicked undo tab close and got the time back and then clicked "Back" to go back to the "Ask a Question" pageboy all of my draft was now gone.
In Microsoft Word for instance I no where to find the autosaved text filed to recover most of my work. I don't know if such a thing exists in Stack exchange tools, but it should. I can't imagine I'm the first to lose 10-20 minutes of very boring documentation work to ask a question here.
Thanks
