Universal Tiles (the official name) haven't been used in ages. They are 
currently on my short list for removal because they are introducing some 
deep and entirely unnecessary dependencies between the tools and 
specific Morphic/Etoys classes.

If you are looking for helping in this area, start from CodeHolder's 
usage of contentsSymbol == #tiles (browse sender of #tiles to find these 
and more) and then carefully work your way outwards by fixing or 
removing methods and references.
