VizLib Button Selection

Hello,

I assumed that when you clicked a button, developers would have the option to make that button look different than than the others to indicate that it has been selected. In my use case, I had three buttons, each of which would update a single variable (Projects, Service Requests, All). I was surprised to learn that if I clicked (for example 'Projects'), I couldn't make the background color different than the other two.

Thanks for your work.
