Hey alt_, and thank you for your comment.
The system was initially designed for Android, so most of the features (including the comments) are currently available only for Android based devices.
Regarding the blurriness of the buttons - will fix it - thanks.
Thank you for you help.
Design is a bit plain and the button images look blurry and out of place on a retina iPad. I also didn't find an obvious way to comment - is that not yet implemented?
