God some of you guys must be showing early signs of dementia if you think that the BG/BG2 interface is with out flaw or is significantly better than the PoE interface!
First the inventory screen:
BG/BG2: Can only see one characters inventory, fine if your soloing, pain in the arse the rest of the time, WAY to much inventory micromanagement as a result pick up some cool armour and want to give it to the fighter, so drop it on his portrait and it doesn't transfer. So go to his inventory and it's full, so try transferring something out to free up space but the character you pass it too also has a full inventory. Send the next 5 mins shifting around thing and turning consumables into stacks or moving them to the appropriate sub container before you can give the fighter the armour you wanted in the first place NOT FUN (though maybe you enjoy that shit)!
PoE: Can see all characters inventories at the same time, and easily drag an drop between them and the bag of holding (Stash), massive improvement.
BG/BG2: Got some awesome new armour weapon/amulet/armour that modifies some stats equip it and want to see what it's done, have to change screens to the Character page unless it's HP or AC.
PoE: Can see major stats for character in the left window!
BG/BG2 Spell casting in game interface: One button all spells, LONG LONG list with arrows to scroll through move to quick and you'll scroll past your spell and have to scroll back to find it! Only 3 shortcuts (unless you managed to use the hot key's to some how bind every single spell and remembered them). Want to cast a level 8 spell you've not added to the 3 short cuts (Ops make that less than 3 if you've dual/multi classed), click spell button, click scroll arrow, 1, 2, 3 times click spell (4+ clicks).
PoE: Spells cleanly separated by spell level, want a level 8 spell, click lvl 8 spells click spell (2 clicks), except maybe you know you could use the really easy hotkeys (if slightly broken in latest build) find spell press key...
BG/BG2: Levelled Character abilities, hope you remembered that the new abilities went under the diamond at the end of the screen, otherwise they may not get much use...
PoE: Character abilities clearly displayed!
I can go on...
Now I'm not saying that the PoE interface doesn't need some additional improvement but take off your bloody rose tinted glasses when looking at the BG/BG2 interface and realise that it had some massive issues as well.

Is NOT better than this:
