Would it be possible to have two separate 'Define Overlay' panels? For example, right now, if there is no overlay, there is not define overlay panel. When I add an overlay, I get the panel. If I were able to add *another* overlay, then there could be a 'Define Overlay2' panel pop out over the other one, whose viewing I could toggle on/off-- much in the same way I can have a 'Define Datamode' extend over the 'Define Overlay' panel, and then retract. That's the kind of behavior/placement I was envisioning.
The only new space needed in the main controller would be a second set of small 'Define Overlay2' + 'See Overlay2' buttons, to be able toggle viewing on/off, as well as an 'Overlay2' button to add a second overlay to the data set.
