Why not pan with the mouse? And what does that have to do with party management? You just click on a party member, then the person you want to attack, or the place you want to move to or the spell/ability you want to use and its target if applicable, or make a rectangle around all of the party members for group actions, what's irritating about that? All the spell books etc have easy to use mouse interfaces too. I guess you could have all the party's inventories in one screen instead of separate for each but when just moving items from one to the other you'd do the same number of clicks anyway, you just drag the items you want to transfer on the person's portrait instead of their private inventory screen as it is. Most of the IE games have amazing controls and GUI, convenient, speedy and easy to understand, few RPGs have done as well since, even later DnD games did worse.
