MusicVillian, Some customization is available but, I don't think to the extent you desire.

Are you aware BiaB has two GUIs (PG Music calls them screen modes)? You can switch between the normal and minimal screen modes by using the keyboard shortcut Ctrl+T or by selecting a screen mode button located next to the DAW button in the DropZone (top, left side of the screen). The mixer can be moved, resized or not displayed. The mixer can even be moved to a second monitor but the move does not persist between sessions. There maybe other customization's I'm not aware of.
