Welcome to the forums, Ronko. Congratulations on your new HTC One!
I don't have mine yet, but I've been reading in this manual/guide and tricks and tips site a bit: HTC One Manual and user guide
... check out the links on that page for deeper info.
A One user will chime in with an answer to your query about the panels/screens etc, but I thought that site may be useful to you in the mean time.
