"clunkier than the old system"
I am sorry Bob, but I disagree with you 100%.
People fail to learn and adopt to more efficient ways, instead asking to keep obsolete methods, which makes program bloated with with unneeded complexity and redundancy, scaring new comers...and then complain about bugs.

Instead of bashing fantastic new feature, I recommended spending 20-40 minutes with it.
Here are three items of new way that I am aware of that makes new method not whole: An option to "ghost" play, meaning without affecting original. Option to preserve original tempo. Undo coupled with Undo history. You can easily overcome all these by making a copy of original project and working with a copy. I do hope PGM will address these.

New method benefits:
No mousing or scrolling through different menus & jailed pop up dialogs, waiting for memory generations that will not place the style unless you exit and repeat. With new method, unlike old picker you can navigate through the whole project and hear exactly what and how it will sound at a particular place, with your chording , preserving settings and VST instruments you have in your project. You are free to edit project while MTP (Multi Picker Library) is open and switch between the two. You can swap out RT's and other content on the fly without closing MTP. You can quicky audition dozens of styles on the fly with your chordsheet which took 10 times longer with previous way.
