I have been looking for this functionality myself, but since I run with my other windows visible in small windows using maximizer I can just look at the bar there so I get by with that, but I would love to have a more detailed view right on my unitframes. Also if someone could modify RestFu(or RestedFu, cant remember exact name atm, its a mod for fubar that shows the level, xp and rested xp of all characters on your account) to show the other accounts used on the same WoW install, that would be great. A similar modification I Know is wanter for other mods such as the ones that show bags and bank items across characters but not accounts.
