The containers and rotten food can't be picked up.
Yes they can.
They can be dragged into inventory just as you do with the teleporter stones and the bedroll (just like the portable bed in DD, there's one in BD you can carry with you wherever you go). You can sleep with a click in inventory. Or drop it on the ground if you so wish.
You can drag into inventory all those packages, chairs, barrels, alchemists herbs on little plates, garbage, rotten food, books, and all sorts of stuff. Maybe you'd like your own personal storage barrel in the middle of town - try moving one! <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> It sure all looks like junk, but who knows? Maybe someone will discover some neat trick you can do with some of that stuff.... <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
