The dev is awesome! They fix issues very quickly, often implement suggestions, and provide clean, consistent add-ons with very useful features. My members enjoy being able to select a mood, and the various interfaces and display locations for the add-on are great!
My only complaint, if you can even call it that, is I needed to manually import each mood. There were over 100 (as banner images) in the mood pack I downloaded from a third party, and it was a bit tedious adding them all.
But once done, it's awesome! Thanks!
