When plotting radar data, especially with multiple stations on the same map or with scripting, it would be nice if DA could be configured to discard data from stations older than a specified number of minutes, or have a time selection feature similar to the one for METAR and upper air data. Radars go down for maintenance or other reasons fairly often, sometimes for days at a time, which can mess up a composite image pretty badly. Currently, in this situation, the last available radar data is plotted from that station, along with the current data from surrouding stations. So on a clear day you might see a blank map everywhere except near one radar site, where there would be an image of a line of thunderstorms that moved through two days ago when that radar site went down. Instead, it would be nice if that old radar data didn't plot, and the current data from the other sites overlapped that site's area as much as possible - just as if you didn't select that site at all for radar data.
