Meh.

Awesome idea, but…
* Not retina-ready
* Flickers when coming in and out of mission control
* When switching back to desktop from full-screen apps, desktop often switches back to whatever I have as my desktop background, then back to Kuvva wallpaper
* Aggregating favorites is very inefficient
* No way to select a certain wallpaper, must switch between (like an old TV with no number pad…)
