Hey Matt. Pretty cool.

* Would be nice to be able to upload files (or drag and drop them onto the board). * Would be nice to be able to affect the z-index (bring stuff to front/push to back). * The appeal is the free-form drag anywhere aspect ... I'm not sure how much grid/list add to the app.

My goal with my project (http://www.thetaboard.com) was always to strive toward the simplicity your app exhibits (other requirements/features kept me from getting there) but I think there is a space for something like cork.io.

Good luck!
