(the latter [Rose's macros] use their own fonts, which is a large reason for their superiority).
Without having any knowledge of Rose's package, I would much prefer to have complete flexibility in the choice of labels. Two reasons for this are: (i) labels in the diagrams should agree with those in the text, and; (ii) fonts change more rapidly than diagram styles. One further point comes to mind. If other fonts can't be imported, then perhaps other macros can't be used either. For example, one might use arrays to label linear transformations. I suggest as a design criterion that Any box should be admissible as a label. Barry Jay ==============================================================================
