Hi,
I just wanted to report that vector brushes preview end up looking really weird when switching back to Vector Persona from Pixel Persona. You can reproduce this bug, following these steps:
Go to Pixel Persona
Open the Brush Panel
Deselect Show as List.
Go back to Vector Persona and open the Brush Panel.
You'll get vector brushes previewed as thumbnails like the attached image. Since you cannot apply list to thumbnail previews on vector brushes, I assume this is a bug. If not, this looks really weird, anyways
Cheers,
Enrique
