Mute Button Location
The mute button in calls/meetings is RIDICULOUSLY close to the end call button. Anyone not using a hardware button to mute themselves has to manually click right next to the end/leave call button. This is true in both the maximized and minimized size call windows. On top of the location, the leave button's larger 'hit box' size means that a click in the middle is interpreted as an End Call action instead of Mute or Inaction.
From a user experience perspective, this is confusing. No matter the setting, an individual is more likely to hastily need to mute themselves than to leave the meeting. Why place the two buttons near each other at all? Why not remove the 'end call' button to an individual location on the screen separated from the control panel?
