Screen Sharing - add an "actual size" button to show the presenter's desktop resolution
It is difficult for viewers with poor vision to see desktops that are shared. HDMeeting and other videoconferencing apps have a UI element to show the 'actual size' of the display resolution.
Users can use the zoom button to enhance the Teams call controls, but not the shared screen.

I want to add that Skype for Business has this option and it is the only thing blocking us from migrating from Skype for Business to Microsoft Teams.
Example: I have a full hd monitor with a 1920x1080 resolution. My peer has a 4K monitor. If he shares his screen I cannot see what's on his screen because his 4K resolution is sized-down to fit my full hd resolution.
Instead, I wish to be able to zoom in to different areas of his screen like Skype for Business offers a "original resolution" button.
