I would find it useful if there were another option in the "Full Library Search" panel: "Find only in titles of entries". I just recently needed to find an entry in a user book. I knew a very common word was used in the title, but if I searched for that word, I'd also get lots of hits in the content of entries, where that common word would likely appear in every entry. If I could have searched only the titles of entries, I would have been able to find what I was looking for sooner.
