I realize that notch said signs were almost done, but one thing I noticed is that they can only be placed on the floor. they should also be able to be hung from ceilings and walls, much like shops you see in medieval/renaissance towns.
that noted, torches should be allowed to be hung from the ceiling as braziers. And now that we have the potential to write on stuff, we should be able to use the bookshelf. Imagine it like the chest, but all the slots have book icons in them already, and you can open them up to read them. Only the owner of the shelf should be able to write in them but anyone can read them. And to finalize this rant, no place is better to write then an underground base. how about a writing desk to create book items and notes. notes for leaving clues to buried treasure ( yay ) and books because everyone loves to read while they wait for the sun to come up!
