Add option to overlay of imagery and chart layers
Occasionally I find it useful to view imagery and chart for a harbor at the same time - the image alone gives me general information on mooring fields, floating docks, and anchorages, but the overlay would give me specific navigation information on moorings, docks, and anchorages.

This is going to be a little while as we’re working on a new vector engine that will include a global vector map. Our rough estimate is mid to late 2012.
