I won't be much help with your questions, but I'd like to see the answers too.

I just started messing around with Macaroon last night. I managed to get 1 of my accounts set back up, and all the binds re-set.
I was using bongos before..and I was just too lazy to change to Trinity. But I really like that you can create macros in each button.
I'm trying to get used to the whole mouse-wheel used to set up everything..thing. But it's growing on me.
