This is a bit of a pipe dream, I know. But I would love to see an api (like a webservice) that programmers could use to build mobile apps that allow the user to send macro rolls to the game. Personally I want to integrate this into a character sheet app so that I can track my character on my tablet and send rolls in. It would also be awesome to just have an app where a user could define and organize macros how they want and then send them in, This website is awesome and it is very playable, but screen real estate is a precious resource and a user's (especially a GM's) number of macros can get unwieldy fast.
