So here's something I'm wondering about in the full game. We get two proficiencies from our background currently, yes? However, said backgrounds provide several other benefits according to the PHB, though a lot of them aren't particularly relevant in act one. They could be noted, however, like how the criminal background gets a completely reliable underworld contact (and there are a few less than savory types transporting to Baldur's gate that could pass a message off to your contact there, letting them know you're alive, though with no immediate benefit) or how having noble background has everyone treating you with more deference ( you could have, say the duke's advisor treat your character with added deference as a cosmetic difference [and perhaps some down the line benefits from such] when you rescue her).
Perhaps, also, when you reach Baldur's gate, your background also unlocks a quest chain that plays off of it and is different for every possible background, to help them feel more relevant and interesting.
Just some thoughts
