Sort out the basics
As someone who has to use Teams for work...
It uses a ludicrously huge amount of resources.
Plenty of bugs that need fixing, some quite irritating, my 2 most hated bugs are:
e.g. 1. sound / video often fails to work correctly on meetings, especially if you have the temerity to switch between different camera and microphone / headset setups*
e.g. 2 Intermittent, but quite often Teams suddenly stops sending you reminders of meetings. Which can be a PITA when you are deeply focused on work & easy to lose track of time & you rely on the annoying noise of a meeting alert to snap you out of dev mode & into meeting tedium mode.
* When WFH will sometimes use webcam (with inbuilt mic) for video and audio, other times inbuilt laptop camera and mic (depends on how good the video quality needs to be), and sound output via laptop inbuilt speakers. In the office will use a headset (don't do that at home as prefer not to have kits on my head as it's not comfy) but obviously in office do not want your audio to disturb others.
Please fix the many faults before adding yet more (doubtless even more resource consuming) frippery.
