Filter Selection in 3D view and in outliner

I am wondering why a filter selection exists for the Dope sheet, NLA editor, and graph editor, but it doesn’t exist for a 3d view and for outliner. It would be a really great feature to have in the 3d view and outliner.

Yeah, would be even better if there was an option to set: Global or Local Filter Selection

how would one go to suggest a feature like this to the developers?
