Attractmode has filtering, add/remove games from favorites, add/remove tags (which can be used for dynamic lists), and can program your own layout if you want. There is lots of community created themes on the attract forum. RetroFE is very similar, so it might have same features. It’s worth checking out. Not sure about big blue front end, but it’s awesome if your a Capcom fan. Extremely thought out UI for adding and organizing games.
