isn't party1 yourself.

I like the Jamba idea myself... but I'm a little older school and I have 5 macros on each account for setting focus so when I press ( replace leader with toon name, replace alt1 with toon name )
F6: set focus to leader
leader: /clearfocus
alt1: /focus leader
alt2: /focus leader
... etc

F7: set focus to alt1
leader: /focus alt1
alt1: /clearfocus
alt2: /focus alt1
... etc

I also have each toon tell me who they are following with
/p focus %f

and my follow macro is a simple
/follow focus

Jamba sounds a lot easier to setup ... and I use Jamba ... go figure
