Description of the new feature/enhancement

Currently, if we have two instances of Terminal running (one elevated and one not), we get two identical icons in the task bar. This can be a slight inconvenience when Terminal is set to minimize to tray, as often, it requires that we activate both windows to determine which is the one with which we actually want to interact:

An improvement could be as simple as a change of color, or a small shield badge to differentiate the two icons. Or even better, (if it's even possible) consolidate the icons into one, and allow the user to select the desired window from a context menu.
