Quite often when writing a forum post on a smartphone, I accidentally press the back button so the browser goes back to a previous page. When I then go forward to the page I was writing the post on, all the text has gone. This is what used to happen in the very early days of EasyEDA but some time around version 3 or 4, the forum post was made "sticky" so as long as you only went back and then forward to the same page but did not do a refresh (F5 key), the text was still there. Can that behaviour be brought back please? It is very frustrating to write a reply only to loose everything, including things like screenshots, just because of an accidental key press. For example, I am passenger in a car at the moment and bumps in the road often jog my fingers. Thanks!
