Ripper,
It's a good thing you didn't rename the artwork. For the translation of the artwork I've contacted Wichtel. He translated the artwork into dutch, after I provided the wright text. Maybe you can do the same.

The "forced" refresh starts if you are on the first screen and push on the time after "Updated: xx:xx"
The arrow is for the "Shortcut Groups". The first group is presented on the main screen, the second, third, .... are presented after you push the arrow.
The bleu button at the bottom has to function with a set "apps-6" that Wichtel provides on the first link. Getting it to work is not easy (a lot of questions in the german forum).
If you're not sure what a german word mean, please feel free to ask. I speak Dutch, German and English.
