Allow the input categories tab buttons to be on/off toggles so that we could have more that one category of inputs visible at a time.

For our worship service I have a basic set of inputs that handle typical camera shots, titles, etc. Then there are specific groups (categories) of cameras, titles, videos, powerpoint/ProPresenter for worship songs, the sermon/message, communion, etc. Adding the ability toggle categories on/off would streamline the input selections to only those currently needed, freeing up space and reducing the chance for screw-ups - without having to duplicate the basic input set in every category.
The ALL INPUT tab would work as a toggle as well: on=show all inputs, off=show selected categories.

This could be an opt-in feature to assure backwards compatibility with existing presets.
