Matt,
it's a known fact, that probably the biggest drawback of BIAB (for new users) is complexity. Much of that complexity comes from various redundant segments left in software that contribute to expansion of extra menus, semi-obsolete functions and of course bugs. PGM, it seems, leaving most of such items as a safeguard for those users that might need time to adopt, but then "adaptation" period lingers forever. I believe Peter and team done a great job of re-creating familiar way of picker operation in MTP, but leaving all other pickers indefinitely would be strange at best. Like trading a donkey for a car, but then refusing to give up donkey, buckling him on back seat to ride along, to keep company...

While PGM rarely asks for feedback, I believe this thread is optimal opportunity to discuss this among users and come to some form of general consensus, giving PGM a glimpse of specific issues customers are faced with. I feel a year should be more than enough to gather such feedback and make certain changes to MTP Library, so it becomes a central content hub, retiring obsolete items and making software more consistent...for everybody.
