NMEA GGA messages carry information on correction data age (dgps_age in external/nmea/sentence.h) and correction data station id (dgps_sid), if correction is present. Both information items are substantial for assessing position quality. Not only right before initiating a measurement, but also logged inside attribute data of GNSS-created GIS objects (for later evaluation).
Therefore, it would be good, if both values could be displayed inside the position information block and if new @position* / @gnss* variables would be exposed.
