Is that such a difficult thing to imagine? really?

Or how do you want to translate from English to English ? ;-).
But, if you do have another idea in mind, it would be great if you could share it!
P.S. I don't think this belongs into troubleshooting. You can move this discussion by clicking edit and than choosing the forum from the drop down menu.
