"Book with text" is the tooltip for any book that is not empty.
It would be much more useful to display the actual title of that book as tooltip.
Same problem with chests - currently, an extra sign is needed,
and that gets unwieldy with more than a few chests.
So, I propose to add a title-field to chests.
Also, how about using different wood-textures on chests ?
Maybe also allow to add dye to paper, and books.
