being able to use a telegram client for matrix would be great, but the problem with matrix is not so much the UI but the complex handling of encryption which can sometimes fail. unlike deltachat which downgrades on failure, which is bad, matrix stops working on failure, which for the average user is worse. a better UI won't fix that unfortunately.

still i like the idea. but deltachat also has a nice UI, and for matrix i use fluffychat which is also quite nice.
