Aside from the display niceties there is nothing you can do in macaroon that you can't do with /click and creativity. Unless of course you use more than the total number of macros you are allowed. But I have 5 teams and still have about 10 free macro spaces on each even with all 1 scenario type macros.
Hopefully you'll be able to continue, I was addicted to flexbar when it still let you switch buttons and macros in combat. That was a hard switch for me, but I would have to say that one experience made me a better and more thoughtful player...at least as far as planning out setups and macros are concerned.
