I have suggested the idea in the thread started Curious Labs some days ago (got no answer...) I have not changed my mind since : modular plug ins would certainly sell a lot. But this means that the program must be constructed to accept them, and that any free lance progammer must be allowed to develop a plug in. I don't know anything about the first item, and the first version of the EULA did not let me think that the second was in the air. The only proble with modular plug ins is that at some point you may get incompatibilities. To be continued ?
