Filter for Tags

I have several thousand tags and it would be nice to filter or refine them by keywords within the tags. Many of my tags concern the same subject (e.g. “church bells”) but I have them labeled 3-5 different ways: e.g. “bells” “church bells” “bells (church)” etc. It would be ideal to highlight all tags containing “bells” or “church, bells” and then rename them all simultaneously.

This request echoes an earlier post from 2020:

“I’m waiting better tag selector. Some my thoughts: ability select multiple tags and multiple lists at the same time; ability filter tags and lists by the name and selection that remains after new filtering; and navigation and filtering only with keyboard of course”

Yes, we agree – a new tag selector/manager is sorely needed.
