Have per device filtering. Maybe using the same color method. For example rather than having to filter the entire network and have certain devices or passwords bypass it you have groups. ex kids devices are Red you can assign all kids devices the red color and then give the filter options you want for the kids group the red color as well.
I will say that also you can create multiple filters and apply different ones for passwords or SSIDs.
I think this option would be great! if we can assign colors to devices and filter based on the color would be great!
