Another thought would be to have a way to cancel the edit. once in edit mode, regardless of if you make a change, the only options are to delete or send, which then shows the message as edited even if you made no changes.

You're probably sick of it, but this is pretty streamlined in Slack and exactly how I'd love for it to function in Teams.

1. Up arrow to edit

2. Choices:

a. Edit the message and hit enter to submit; focus is returned to main chat input.

b. Delete all message text and hit enter to submit, message is deleted after a prompt asking if that's the intention. This is done in place of a 'delete' button.

c. Cancel button to cancel the edit, which requires no mouse input as it can be tabbed to (I just checked and you do have the tabbing in Teams, yay!).

Thanks for the status update, by the way! I'd love to see an update on the compact chat as well =).
