do you mean AT&RT or ASR?
It was a rather unspecific and general spur-of-the-moment remark.
Probably triggered by the fact that I realised that I don't have a good understanding of all the elements in the user interface.
But for a part it's also a more general observation.
For example, while 'Advanced Search & Replace' is well-known and familiar, there also is a 'Multiple Search & Replace' feature.
I never even clicked that one because I have no clue about what that does or why I would use it.
More specific about the AS&R panel:
Here's a screenshot containing some highlighted elements.
These are buttons that I have never clicked, because I have no idea what they do, and/or what the differences are between similar named buttons.

Again, my comment was rather vague and un-directed, probably a bit lazy, and maybe not very helpful.
And the fact that nobody else voiced any sort of agreement on my observation probably means it's just me.
But still hopefully somebody will one day write:
Additional Tagging & Reporting Tools for Dummies.
It surely would help me.
P.S.
Even though you there is a comment in CAPITALS about it, I still feel that it should be more clear what the check boxes in front of the functions mean.
It is a function that can very easily raise havoc on a music library. (it has happened to me too)
There is no tool-tip when hovering over them, and no pop-warning when you have activated one.
Most users of AT&RT probably have learned what that does the hard way?
