UI improvement of default web client

[alci63]

Hi,

I think some small changes would benefit the default UI for occasional users:

1. the logout icon is located just below the close menu icon. More often than not, a user that changed his camera setting will logout instead of closing the menu

2. no feedback on Enable button When clicking on Enable, no visual feedback is given to the user until the browser asks for permissions, which may take a few seconds. Users often click multiple times, and will quickly conclude it does not work. Teams or Google Meet also ahve this browser "latency", and solve this issue by displaying a message telling user that she will need to give access to her camera / microphone.

3. No button to stop camera There is a mute button, but no button to stop sharing the camera. It's not clear if Disable will only stop the camera or both camera and microphone.

This are just my 2 (euro) cents, after testing galene with users not knowing anything else than Teams.
