It would be valuable to be able to write some notes describing what the build does (using a window similar to the Multiparameter "specify multiparameter information" window) and access it from an [Info] button above the module grid.
As in this mock-up:

Also, consider adding MNotepad to MXXX (but do the above anyway).
