Is there a way to open the inventories of both characters at the same time? Or the inventory of even four characters (with companions/henchmen)? Imo it's a real chore to transfer items between characters....would be much nicer if you could do that while all inventories are open and you see exactly what everyone is carrying around...
Yes, there are actually two ways.
1) As an example. Click on Roderick and press "I". Then click on Scarlett without closing Roderick's inventory. Pressing "I" opens Scarlett's inventory right in front of the still open Roderick's inventory. All you have to do now is to drag Scarlett's inventory a little bit to the left so that you have two inventories next to each other.
If you just want to transfer one item from Roderick's inventory to Scarlett:
2) Open Roderick's inventory and drag the item from the inventory to Scarlett's portrait on the left side of the screen ("magic pockets"). Now, Scarlett should have the item in her inventory.
