Not looking to be negative, but we tend to get these topics every so often and honestly there's very little that people are looking for.

The real limitations pretty much stem from non-Windows multiboxing programs. Judging by the threads I've seen over the years, programs for Macs are pretty limited in their functionality leading people to go without all the bells and whistles or running BootCamp so they can use ISBoxer or something else with the features they want.

I'm not trying to discourage you, there's always room for more options. I just think people are going to be hard pressed to come up with ideas that aren't already part of currently available programs.
