Messenger is important to me.The problems it has are fixable.1. I write in a foreign language and as my language is not supported I get red lines under everything I write. This is on no other Messenger platform that I know of. Just fixing this problem would make it a 4 star and a recommend for everyone in the world.2. Active users. Facebook should know that people generally don't use the "who's active" window and it is annoying to work when something is constantly updating and re-rendering on the screen. I generally scroll down a bit just so I don't have to see this disturbance. These are people I never talk to and it seems weird to show this on the main screen of the application.3. File-sharing. Why can't the file-sharing be like online. There are too many files types that are not supported.4. Dropping files or images into the input field. It sometimes doesn't work for some reason.5. Search. I'd like for the search to be structurally better. It is hard to find things.6. Calling. When I end a call I have to manually close the window for the call. Why doesn't it close by itself when the call ends? I hope Facebook engineers get on this and make native apps great again!
