This is the one thing that has kept me from completely switching to Gmail. However, since these edits are not actually written back to the email, but stored locally (even synced with Signal on other machines), it does no good since the Gmail app on my Android phone and tablet can't see the changes. BE VERY CLEAR you're just editing and storing locally. The original Gmail message unchanged. I combined two emails, deleted one of them, and checked it in the Gmail app. All I see is the original message, but other other is deleted. This will just confuse most people. Unless this can change the message on Gmail, it is useless to me.
