So one of the things I love about this game is just how detailed the character models and outfits are, and how we've got a pretty good range of options. But as with actual D&D, I have way more ideas for characters than I will ever play, plus character creation is just part of the fun.
What I would just love to see would be either an option on the menu, or a standalone program, that's geared entirely towards creating characters so I can take screenshots; skip the mechanical details, just let us pick from any gear in the game and give us a nice big fullscreen view with a choice of backdrops so we can take some screenshots.
I could see this being fantastic for creating visual aids for meatspace D&D, e.g- instead of trying to find artwork in image search, I could just knock together an NPC using the BG3 character creator and snap that instead.
