BG1 at least had a lot of different sprites for them, but it would be cool if they had an "item description" view that made them look like something worth coveting. I see all this as being not too hard to achieve in a way that's automated, so as not to overburden the player, but while still giving it some flare.

Otherwise, gold as only currency is ok for me. As main thief, it's hard for me to imagine what stealing money would look like with multiple currencies. I mean, that's the main reason why there's no automatic money accounting as a resource and you have to carry the gold around in your inventory. Would be annoying if we have two more stacks of currency in the inventory. Up to now there are enough items that are not even properly stackable... In addition, there would be the meticulous counting of pennies when bartering... Like old grannies at the supermarket checkout...
