It would be nice to be able to preselect/queue SIDs/STARs/IAPs etc. to have them readily available. For example, in the enroute environment I may have an Enroute Low Altitude chart displayed. When told to expect the ABCDEF Arrival and the ILS RWY ## approach, it would be nice to pull up those plates for familiarization and still have them readily available after switching back to the enroute chart. Perhaps a Most Recent Plates list that would only require a couple of clicks to get to the desired plate.
