Ok. So ever since I installed Mezzmo, I've loved it. With the help of the support staff, some minor snags have been worked out and all is well.
Now planning to work with some of the other features, I scanned the forums regarding the different playlist options and have come to realize that I may be missing out on some things.
In my Library list, I only see the folder (and its sub-folders) that I added when setting up the library. Also, I see "Search Results". Many of the posts here suggest that there should be more in this list. Am I missing something?
here is a screenshot of what I see in Mezzmo:
