1. Notifications are shown in gray instead of yellow. Yes, I understand that this may have been a style decision, but they are notifications. They have to stand out.
2. Selected list icons have got left/right edges. This causes unpleasant visual effects in multi-column lists. Try selecting an entry from the phone log or contacts.
3. Volume/position slide in the Video Player shows up with the wrong background.
4. There is a gray frame around the screen in the Image Gallery.
5. The default background color (gray) messes up some other apps as well, such as BatteryGraph.
6. Sliders (such as volume slider) show up some color-banding.
7. Please, make shortcut icons larger, the same size as in the original themes. There are really other ways to save desktop space, without making shortcut icons look truncated.
8. Contact shortcuts come up in green, without contact faces.
