Make chat more like Skype
The following could be added to the chat feature:
Video calls could have an volume control from within teams. As adjusting the overall volume for the pc isn't ideal.
Add a caption option, the same as skype. In my team we add our location and mobile number so everyone knows who's where.
Add groups/dl to favourites on chat (the same as Skype)
Add screen sharing on chat (currently I can only see it during a video call)
