Tagging Suggestions / thoughts in L8 Library

Let me start by saying that I didn't tag my library very much in previous versions.  Mostly because I was struggling so hard to just use it as a Bible study software, the last thing I had time for was customizing it beyond collections.  Anyway, I usually tagged a resource that I wanted to find easily, because I had such a hard time find my resources in previous versions.  Now that we have this fantastic drop down library, (and I'm finding that I'm actually ENJOYING my time in Logos instead of wanting to throw my computer out the window), would you mind sharing some other uses that you would have for tagging?  Maybe even share a screenshot?  Thanks!
