Is it possible to have multiple inventories available to one character?
Is it possible to have two inventories from two different characters on screen at the same time?
These questions are a little bit whimsy, but I think I could get quite a nice effect if I knew vaguely how to do it.
Thanks for any help.
I don't think that's possible. But you could make a second, invisible character for the protagonist's "second inventory", I guess.
Here's an example of how to add a second inventory to the player character (not technically though, each character has only one inventory).

You can have more than one InvWindow on the screen, sure. You can put two InvWindows on one GUI, or use two GUIs with one InvWindow each.
InvWindows have a CharacterToUse property; it's changeable during a game via script and sets which character's inventory the InvWindow will display.
