autosave for the posts?

could autosave be added to the forum posts? For its quite irritating if connection happens to break (or something other that makes the post vanish) and it sometimes empties everything that was written.
and sure its not that much of a problem with smaller posts but if the post starts to get over certain amount of letters its really annoying.

im not sure if there is such option on PC but at least it seems there is no such thing on mobile.

This would be a nice feature. I keep forgetting that when ever you press Ctrl and Z to go back (usually by one word in word) it pretty much takes all my work back to nothing. A save feature would prevent me from losing this work.
