There's still something quirky about the first satellite display jumping between two Svs for a while. But it appears to stabilise out.
Altitude is a bit off.... unless someone elevated my city by about a million feet.
HDOP appears to work - I saw values of between 2.8 and 3.7, which sounds reasonable (IIRC about HDOP).
There needs to be a charctor space between the number of satellites and SV which would make it more legible.
Shading now works great.

Is it possible to add a signal strength scale? I haven't looked to see whether the range changed, but it should be possible to fit a scale in the first column - a line of VFDSHADE_MEDIUM, with dots of VFDSHADE_BRIGHT every 10dB (starting from the first round multiple of 10dB obviously.

Oh, I suspect that once Long and Lat are added to the sat screen that elevation would probably want to be moved to top left, and long/lat kept together on the right - in line with keeping the most utilised information away from the 'fascia bug'.

Thanks again for this great app.
