Messenger 4+

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!

First of all -- it is amazing how I can use Messenger app on my MacBook because I wouldn't like to have an iPhone and laptop at the same time, since they are all connected to the same account where we can communicating like iMessage, Messenger, WhatsApp, etc. Honestly, once this issues fixed for not receiving any notification (because I am deaf and i couldn't hear if it is ring me), for major issue is CPU and battery: my CPU is too high and battery went drain too fast, but my laptop isn't very old because I recently updated my new laptop since 6 months ago. By the way, it's beautiful feature when I can be able to enable dark mode to reduce my red eyes on the screen at night (still, doesn't help 100% due to screen). I would give three out of five, but this is still earlier verision of Messenger for macOS. I removed Messenger off of my computer but I will be looking forward to better-fixed version that come friendly support with our (in the world) computers' hardware. It's kinda funny when Messenger works like a charm on iPhone and iPad, but MacBook...

This app is just fine on mobile platforms. My brand new Macbook Pro with 8GB of RAM was running the fan like crazy and couldn't even keep websites loaded. I checked the wifi, closed and reloaded tabs, did updates, etc. Nothing helped, and I was feeling like a I might have a serious problem. While I am pretty tech savvy in using the computer, I am not strong in the underlying workings of software and hardware. I did a little research online, which advised to check the Activity Monitor. Facebook Messenger was the top CPU process - 60% or something - with others nowhere close to that number. These were other programs with far more computing power - Google Chrome, MS word, iBooks, etc. I only had messenger open in the background. I uninstalled the app. Immediately, fans turned off and everything started working again. I did some more research and found out that many people were also having this problem in both Windows and Apple. This is a HUGE issue that Facebook needs to address before continuing to offer this app. It completely cripped a brand new computer just being open. That is unacceptable!
