Hello,
In the Reference File Manager (RFM) if we could have a "radio button" next to the GTV's, that showed black indicator of which GTV is "active" in that Reference File, and have it grayed if you selected a GTV and then toggled on/off some layer(s).
Another helpful thing, would be to have the layer where each Reference File is, listed to the right of the file name. If you then click on the layer name, you could make that layer Active, so you can determine which one is which.
