analogy:

My Mom wasn't a messy person but she had a weird idea of order and she adhered to it. Her organizational scheme didn't make sense to anyone else. One day my brother decided he was going to help her by cleaning her house and rearranging the mess into what he considered a more orderly scheme

My Mom was furious. She couldn't find anything anymore.

Likewise, there are thousands of seats of BIAB in use around the world... many of them used by people whose musical productivity pays the bills. Making a dramatic change to the interface is almost certain to require a learning curve that wouldn't necessarily be a welcome change for everybody.

I hated the new interface in MS Office last go-round. Things I previously mastered I suddenly couldn't do at all.

(just one man's perspective)
