Where you can filter the inputs shown (Video, List, Camera, etc) I noticed not all types are listed in categories. The ones I spotted missing are stream inputs and instant replay, which only show in all. Not sure this is really a bug but it feels like the category list is trying to cover everything.

Possible improvements
I would have thought being able to filter by the colour categories from the main interface would be more useful.

Being able to click a bus and have the list filtered to just inputs with that bus enabled would be useful for tracking down rouge sources.
