I would like a way to determine if a tag in the tag browser is actually used throughout the project. Cleaning up the tag browser of unnecessary tags can be difficult as you are not sure what is being used and what is not. Once you delete a tag you get overlays which indicate you deleted something you shouldn't have but before it gets to this, something like a small green dot next to the tag in the browser, showing it's actively being used would be of great help.

We implemented the core of this idea as the "Tag Reference Tracker" in 8.1.34:

Paul Griffith Is this just on Perspective? What about Vision?

Camille Cordova TRT tracks references to tags across all of Ignition, but is not able to distinguish between use cases from Vision the same way it can in Perspective. That is, you'll see that tags were accessed _from_ Vision, but not from which windows or templates were used. This was a technical/performance limitation, not a deliberate choice to exclude Vision.

In the meantime, you might be able to script this using the getSubscribedScanClasses() and getSubscribedTags() methods of the gateway's Tag Subscription Manager...
