Quest Givers filtering?

[Nodens]

Since Carbonite supports reading quest history from the server, would it not be easy to add a filtering option to only show quest givers with uncompleted quests (assuming as I am not familiar with the addon api)? Or is there such an option there already that I am missing?

EDIT: Hmr, now it seems like it does filter them? Weird..

EDIT2: Ok now I am certain of what is going on. Most of the completed quests won't show up but there are some that do no matter what. Looks like a bug?
