I have essentially added more cells for the name & number of args to the macrotemplate class, allowing them to be edited directly, just like the expansion or display fields of the macro. In my mind, changing the name or number of arguments is no different to changing the expansion or display cells. Presently, an instantiation of the macro updates it's expansion to reflect changes in the template within metrics(). I am not aware of a notification/dirty flag or member function that is called once a cell has been modified. I agree that ideally, this should only be done when the template changes, but that's not what happens with the expansion at the moment & presumably for good reason? Please note, I'm not trying to be argumentative. It's just that I tried to find precedent or hooks for the scheme you've outlined, but couldn't. andrew
