Grease Pencil 3.0 - Brush Library

I know the brush library asset tool bar is on its first iteration in GP 3.0

But here is a suggestion: I would love to be able to rearrange brushes order freely and hide brushes by right clicking them.

the way with the lists feels clunky and rigit

Also importing more brushes through the context menu of that asset browser feels liek a must have as well.
