Enter to send in Messenger?

[Artess]

Hi all. I'm looking for an option to use Enter to send in Messenger, or the option to disable the dedicated input screen in horizontal mode. By default, when I start typing in horizontal orientation, it opens this whole new screen with only the keyboard and input field on it. It only has the "done" button, not the "send" button, so in order to send the message, I have to hit two keys - first "done" to get rid of the keyboard and return to the dialogue with the text typed, then "send" to actually send the message. Any remedies for that? (preferrably without rooting the phone) Thanks.
