Noel,
Sure. Hopefully, this message will not be pulled and we can have a civil conversation.

Issues I have with Utility track picker:

Aesthetics of pickers:
BIAB is suffering greatly from endless menus, boxes etc. Pickers are no exception. They are not streamlined and do not conform to design of second (third) decade of 21st century. Which I think is greatly deterring potential followers. I believe there is very little attention given to this matter. In my humble view, things should get pulled together, not fragmented even more than they are. So having "yet another box" is a bad idea from design point. Tracks (RT's, RD's Midi) are the main treasure of the Box, why have them scattered around in strange, hard accessible places? I think they deserve better.

Functions of the picker:
Before getting to specifics, bear in mind that Utility Tracks are more or less advanced option and to have "styles that work"... is not a good choice there for majority of people who will use these. I am sure these users will have a better idea of what will work better for them.

Now specifics:
No sorting by feel
No sorting by type of instrument
No sorting by genre
No sorting by tempo
No sorting by time signatures.
No Sorting by date
No sorting by set

Noel, personally I think you are asking a very strange question. If you had to pick ONE picker (from what is available) which would you chose, the main or the Utility picker? Second question, if it was up to you to leave only ONE picker for everybody who use the software, which one would you pick for them? And a final question, since all of Real tracks HAVE sorting already, why dumb the picker down, throwing away all that VERY useful function away?

If it was up to me, I would give people the duplicate of main picker (for now) for Utility tracks, because it has the best sorting from what is available. Same format, same window. perhaps different color theme for now, to avoid confusion between the two. In future, I would prefer a SINGLE unified tabbed picker and it will be much easier to do, because pickers would be nearly identical. But I feel if a wrong turn is made now, it would be twice as hard (or even harder) to fix it down the line.
