Currently my BiaB style picker lists some 4,163 styles. Navigating these is a bit of a nightmare at present.
Some things that could ease the frustration:

1. A full-screen capable style picker window.

2. Some way to 'Start // Stop // Start Over // Resume' Playback from inside style picker.
Currently, double-click will preview a style, but anything that stops playback also closes the style picker window.
That's Frustrating when you want to try out a bunch of styles.

3. I love the Real Tracks - I do! But sometimes I want all midi tracks, because I have some great VSTi's.
Other than going through all 4,163 styles and making my own LS3 files or Favorites,
I see no way to quickly preview 'All Midi' styles, (or Midi Piano or Midi Strings etc).

4. Currently Styles can be marked "F" - favorites. Maybe this could be expanded.
M - All Midi
R - All Real Tracks
X - Hate this style
