Set Tracker alternative?

[AlexFullmoon]

UPD: Set Tracker was updated.

Last version of Set Tracker is outdated and bugged, and I'm desperately in need of replacement. Is there any?

Use case: Inventory is sorted/split with AutoCategory. I have, e.g., Sanctuary set. I'd like to add some visual note that says that this set is for healers, preferably via some icon in inventory to check at glance.

Addons I checked:
AutoCategory itself: technically possible, but only by adding separate category per set, and editing rules is not easy. Also some higher priority rules would override that.
FCOIS: AFAIU, it can only read Set Tracker settings and apply its own marks on a per item basis. Not great, since this way is a bit unreliable, it would bloat settings with lots of unique IDs (I guess), and it would interfere with other uses of FCOIS.
