It's a re-post of an old one MultiTab Picker
If it can view the chord sheet at the same time and be able to select by beat for a partial regen, or down the track have an actual Track View.
If they are now making the PLUGIN play the wma sections directly so all DAW's as well as Reaper will have instant Gen/Play allowing you to work in the main Biab and instantly transfer to any DAW not needing BBW4 running in the background. The Transfer Tracks button you now have in the BBW4 Style Picker they can put in the main Biab.

As the PLUGIN develops with it's own code it could be a totally separate product with crossplatform installers allowing users to install on both Win & Mac (on the same month of the year) using the same audio format as you can with Kontakt, Tootrack and others. This will build a new parallel market of DAW only users.
How it works now 6 months apart is not sustainable down the track with double the cost or repeating the same work on mac compared to one crossplatform PLUGIN/PLUGIN Standalone.
