That’s the problem - even apps that would otherwise let me choose won’t let me see anything in the “tagged” view that doesn’t apply. And that includes folders.
Screenflow is a good example. I hit the button to import a file, and the file picker opens up. I then navigate to a regular (i.e. “not a tag”) folder. It shows everything in that folder. The stuff that it knows how to deal with has the filename in black text, and everything else being grey. Folders show up as normal.
In the exact same file picker dialog, I click on my tag. Nothing shows up that wouldn’t have been black text in the above view, and all folders are gone.
So I can’t, for example, tag a project folder and quickly use that to navigate for the half-dozen apps that apply to that project. I apparently have to tag every individual file in that project, and then sift through all those files in a “flat” view in the tag folder.
It would almost certainly work, but I just can’t stand how slow it is. I’ll have times when I open the file picker dialog and the Default Folder X overlay takes multiple seconds to even show up.
If that’s what I have to do, I’ll live with it - but the slowness drives me bonkers sometimes.
