I'd like to create a
Manipulate with custom objects in the control area (like a circuit diagram) that reacts to the user interacting with the manipulate controls (e.g. highlighting the component being manipulated by the user).
Are there other functions/symbols besides
$ControlActiveSetting (which does not discern which symbol is being manipulated) and
ControlActive (which only evaluates to one of two things depending on wether the
ControlActive[act, norm] is currently manipulated or not)? Ideally I'd like to have something like $ControlActiveSetting for individual symbols so that I can query those and change my display accordingly.
