There's no need to hate liking a game! That just means it's fun (yay)!
1. Which furniture specifically would you like to be able to rotate? It'd be a little tricky to rotate crafting stations with the crafting animation, but I could certainly see rotating bookshelves.

I'm still working on the NPC logic (and relationship stuff) - the reason you see Riley out and about is because the farming logic is one of the few that is done. You do have to complete quests with them to help them unlock higher levels in their skills, but they should be able to do basic tasks, and barring that, wander around instead of staying home all day!
