Simple permissions system and ability add tabs.. Yeah, it sounds like AP3 but, being able to set permissions levels for accessing admin functions is what has kept us on AP3. Also, being able to add our on menu tabs (paste a link) and set the permission level is great also.
Good first shot at this guys!!!
Thanks!
I should probably clarify on this. Since J 1.6 has an ACL, I was referring to MC 1.5.1 having the ability to set permissions levels for tabs so that it's easier to customize for standardized rollouts 
Thanks RC Crew!
