How about superimposing the Metars on the the approach charts…Would be nice to see the point you could anticipate breaking out of the clouds next to the MDA/DA of a chart.
How about the winds on an airport diagram with a highlighted arrow and speed. these should not be that hard to do. I take all kinds of notes from the meters and draw them with a highlighter on the IPAD…seems that it would be a useful tool to cut down on the workload in the cockpit while flying.
