And Frogcomposband is still very much being maintained. It's just that there's one guy working on it, and so things take time. If you look at github: https://github.com/sulkasormi/frogcomposband/tree/46db75f898189beeb49d64d735cc3a39e9a843e8 then you can see that commits were last pushed about 4 months ago, which really isn't a long time when it's a lone developer.
