Any thoughts about adding the capabilities for adding comments to the map? A recent development where I had to hand over a large mapping to another developer made me think about the concept for adding comments. The idea is that maps can contain a block of functoids that may all pertain to the same element of work with respect to the transformation between schemas. Comments may be used to quickly inform the developer what the block of functoids is doing in the transformation; much like commenting code. I'm not sure of the visual rep on this concept, but just thought I'd post the idea.
