Lee,
you voiced your personal frustrations by making a case that a few relatively small items that got changed not to your liking or lack of enthusiasm to adopting makes somehow current iteration of the program so bad that it's worth of reverting. That is exactly how I would read your comments if I came to this forum today for the first time.

Overall new MTP is a huge success. Does it need some more work? - sure, fair enough. Bugs reported and fixed - absolutely. But "needs massive improvement" - I strongly disagree.

P.S. My way is not "better" than your way, but I don't believe that memorizing a single key shortcut and / or a nice button on top right is something that should interfere with adoption to one of the most important tools in BIAB. Really. Give it a try, perhaps you will change your mind.
