Ha, it's my #1 pet peeve with parts of SS right now and I let out embarrassingly loud cheers sometimes when I finally observe a settler just getting to their bed for the night successfully. So even if the expansion was just fixing or improving such matters I would be well satisfied. All the bells and whistles in the world don't matter to me as much if they're not working right!
But given kinggath's track record he's well capable of both solving functionality issues and adding amazing goodies at the same time. I'm just personally inclined to keep my expectations in check so that they're more likely to be exceeded.
