As no one could answer my question ;) I have tested NetRemote for some more time, and there you can control everything; fullscreen, I can edit all buttons, you can use custom-ccf and you can put clock and e.g. working battery indicator in the ccf skin.

Maybe Total Remote is a great remote software, but NetRemote is now my favorite and you can edit everything!

Please let me know when Total Remote has some features that NetRemote don't have and I will give it a try (again).
