So, as I make corrections/changes, to my files' keywords - moving/deleting and otherwise, renaming, under @Keywords, as is, updates are not reflected, within the Thesaurus->Keywords. For that, I know, I can just do something, like delete the thesaurus, and then, just re-import, from the database, effectively, installing, a fresh, new, and updated version of my keywords. But, is there a way, to have what's under @Keywords, automatically, be in-sync, to what is in the Thesaurus->Keywords?
The thesaurus is an universal text repository for all tags.
Changes done to keywords don't update the thesaurus.
You can set IMatch to add new keywords to the thesaurus automatically. But renaming, moving, deleting keywords in your files will not change the thesaurus.
For a full explanation and all features of the thesaurus see The Universal Thesaurus (https://www.photools.com/help/imatch/#thes_basics.htm)
