I am currently contemplating on tagging my models as 3rd tier of organising. To me it's more of a search feature than division.
In Connector it would look followingly:
1st tier: 'Folder' structure (taken from file explorer): Beds/Chairs/Bookcases/Decorations/etc..
2nd tier: 'Categories' (items from single folder in multiple categories): Kitchen armchairs, Midcentury archchairs, Scandinavian Decoration, Kitchen Decoration,etc..
3rd tier: Tags: Chair (Armchair, wooden, scandinavian, midcentury, old, PBR,...)
Now perhaps this is how I should approach the textures the same way. The good thing about Categories and Tags is that they are virtual feature outside of physical disc hierarchy so they are flexible to crate and change, and don't affect filepaths.
I think that might be it for me. I once contemplated tagging inside Adobe Bridge but I couldn't get used to having both Bridge and File explorer open at same time. But now with 3rd monitor, Connector will be always ON.
