Of course, leave it to Apple to muddy the feature with a new OS release. I’m not fully sure I think I understand your point about colors, but as long as “portrait” is still spelled “portrait” the Finder would (find) “portrait”. I know finder tags are weird because the system does not allow one to sort or alphabetize them (among other possible issues as you point out). While colors aren’t really that useful to me, I do note that when I add tags in the Finder, the colors default to the same color as previously used.
I DID see that I could (and did) “import” finder tags and see them displayed in the Info panel, but haven’t explored if it has any search functionality.
Thanks Nik.
