I was just creating a quick schematic for a first year student, went to delete a component and (due to butter fingers i guess) hit F12 a split second before hitting delete (the buttons are situated next to eachother on this machine).
EasyEDA being browser-based (Why is the desktop version a browser?) F12 opened the dev/debug menu of the browser, in the elements tab.
Delete then, well, deleted the default-selected Body of the html, leaving me with a blank page.
After this, i couldn't find any other path than to force a shutdown of EasyEDA, loosing all progress since i had not saved and running autosave isn't on by default.
I did not loose anything important, nor anything i had spent a meaningful amount of time on, and i realize that it is sort of an edge case (F12 and delete in such close proximity, butterfingers and unsaved progress) but it seems flawed that a user can (temporarily) delete the entire GUI with a 2-button mistake
