ULTB tag verses collection?

With the launch today of the collection feature is anyone planning to move their ultb entries into a collection?

I have marked one book as "Currently reading". Other than that I don't have many plans for collections.

No, I don't think so - that's appropriate as a tag. I'm using Read but not Owned for my library books, and have made a couple others - Discard for books I owned but got rid of, but want to keep (mostly to remind myself not to rebuy them!); ebooks for, well, ebooks (want to track them, occasionally want to read/rate/review them, don't want them to count in Your Library). I'm also using Wishlist, mostly so I can take those books out of Your Library; I've also removed the checks for Use for Recommendations and Use for Connections, but as I understand it those functions aren't fully functional yet. Hmmm, mostly I seem to be using Collections for stuff I want to track but don't want to be part of my Library.
