      I was just thinking of using the Satellite Number (I think that is unique), so I would just put all the similar ones into a group (perhaps all the AO-## ones together).

       I wasn't thinking of anything clever that automatically grouped them but something the user could setup in the Config to enable quickly enabling the ones of interest at that moment.

      Look inside the TLE and tell me which of those numbers defines a "type" suitable for grouping?

      All the Satellite details window has to (reliably) go on (especially for future 'birds) is the information provided in the TLE.  Every other source of satellite data I've seen is humanly readable, but not formatted for programmatic consumption and interpretation.

      Thanks Krzysztof,

      I had worked that out (after a bit of playing) but I currently only see the first 61 at most.
      So a scroll bar would be very nice.
      I was also wondering if they could be grouped by type, so you can select the particular groups you are interested in.

      Colin,

      you can stretch the window - try.
      Anyway, scroll bar still welcome.

      x2. I have just copied the keps from here:
      http://www.amsat.org/amsat/ftp/keps/current/nasa.all and now can't get to
      the bottom of the list. I guess I could wait until the Satellites I can't
      currently see reach the top but a scroll bar would be nice.

      73,
      Colin.
