here is a little suggestion

(I know i'm very bad with paint, but i don't know how to use photoshop )

in horizontal view, i find a bit uncomfortable that we have to turn the phone to get back to the conversations view. And there is so little space to show the actual conversation, so a resize maybe desirable too.

and in the vertical view, i use the "intro/send" button, so i don't need the extra "send". Instead of "back" i find much comfortable to have an arrow.

This two things are only suggestions, don't take it like requirements. I was just thinking from an user point of view.

Any way, thanks to all the devs

PS: Are the group chats syncing in the last version from tgalal? It's a little annoying having to ask people from the group to talk in the group just to let me see the group chat
