Call Control Dialogue; Either Dock to Desktop Edge, or Permanently On Top of all other Windows..
Quite often when participating in a meeting, using screen sharing and all the other features, a number of Windows get launched. These Windows can then hide the Call End Dialogue. So you spend a number of embarrassing seconds looking for the "End Call" and realise that the person at the other end is having the same problem. There needs to be an option to dock the Call Control to the Desktop edge, or on the Task Bar, or have it permanently on top of all other Windows. The Jabber application we are migrating from, has a "Hub Window" for doing just this.
