Not great.

1. I hate that it’s a menu bar item. I have enough crap in my menu bar. My menu bar is not a junk drawer for apps that think they’re too special for a dock icon. To me, it’s inexcusable to not even give the user an option to remove the app from the menu bar.
2. Some of the artwork seems low-resolution. Even when checking “prefer hi-res” and “prefer landscape”, it gives me artwork that doesn’t fill the display and has black borders on either size. Choosing the “zoom-in” option removes the black bars, but tends to made the artwork look blurry on my large external monitor.
3. I expected more polish from a $4.99 app that is essentially a wallpaper slideshow of public domain images. It didn’t feel like a lot of work was put into the UI. (For example, it was hard to figure out how to mass select items in the lists, I tried holding down “shift” to select several items at once which didn’t work.)
