"But you would really have to be blind not to imagine that we are necessarily going to simplify the whole thing."
Consider me blind. I see all previous pickers as absolutely unneeded complexity that will confuse most users, especially new ones and is a feature creep clutter. And not a hint from developers that these will be retired.

P.S. MoultiPass, I am not sure if you had been reading any external posts (outside PG music forum) by people that had tried BIAB. I've put in a lot of hours just reading these posts over last 5 years, of folks with very different needs/uses of the program. One of the top issues people voice is clutter and complexity.
