It seems a good idea to re-think the way the Library is presented.. The emphasis has been on presenting :ptf and .gpx files for use by MaxSea, OpenCPN etc. Perhaps it might be more useful to shift to .kmz as the key file and have the other two available to those who can use them.
The updated presentation of many of the info windows is already done so they are appropriate to the shift in emphasis. It is a matter of changing the intro. posts.
Stand by!! (For quite a while)
