Parameter Comp wishlist

I wish you could do more formatting with the Parameter Comp.

All you can do is change the comp background, and that doesn’t change the gray color, so its not helpful.

Also, it would be really cool if you can disable the ‘+’ visible in parameter comp. It mucks up the UI layout when you accidentally open one and the comp crops outside it’s fixed height.
Why do un-editable pars still have an open (’+’) option? Everything is grayed out anyway.
