I'm a student, and I recently paid the $30 registration fee. I wrote the author a little bit earlier, who informed me of their 20% discount... they'll be issuing a small refund on Monday. I'm impressed.

My only requests: add speed, and also allow desktop icons to be visible on one (but not all) desktops. Also, default hot-keys are somewhat irritating. I use opt-left/right frequently for text editing. Also, image wells in pref panel need a look over.
