four things i hope to see in the housing system:
1: the ability to craft there (so help me SE if it's like the inns and i cannot craft in my own frikken house!)
2: chest and other furniture to put things in
3: a link to the market board
4: a bell to summon my retainer.

something i'd like to see in general:
1: retainer bells at the outposts. (if i'm out in the upper paths mining silver and run out of inventory space i don't wanna go back to gridannia to drop stuff off. let me just go to quarrymill.)
2: autosort
3: auto stack (if i have a chest i want to be able to press auto stack and fill up the stack in the chest with stuff from my inventory. and vice versa. for an example play terrarria)
