I'd like to make a suggestion about enhancing the icon in the System Tray - specifically, the "tooltip" that appears when a user hovers over the icon.
Is it possible to show useful data, such as the number of connected viewers, in the tooltip? Perhaps this information could use the same syntax as the text overlay facility to allow user-configurable information.
An example of this behavior can be seen in the file sharing application µTorrent, which shows a "snapshot" (not real time) of things like upload/download speed.
