Great interface, and I can definitely see the advantage of being able to add extensions so that it is customized to the specific workflow I am looking for without the junk I don't want.

I think this is one of the first commercial quality meteor applications I have seen, which says a lot of the dev team but also shows meteor is a platform capable of at least getting the job done if not doing it well.

Question: Do you anticipate allowing people to write their own extensions / having some sort of API?
