Yes, it's alot. Is there an easy way of making cgps show more than 21
sats? I would like to see a complete list (e.g. cgps style) of the
sats seen/used. I peeked into the code and tried to fiddle with it to
simply increase the frame height, allowing more vertical space, but I
was unable to make any changes that worked.
