There were some big issues with the old site that have been fixed as well, including editing of maps with over 60 or so waypoints. That should all be taken care of now. There will also be a bunch of different kinds of map markers such as invisible ones, camping sites, information markers, and warning markers, as well as the original flags.
We've also added GPX uploading to the site. My brother has a great map of a 35 mile hike he took in Wyoming. The elevation profile looks fantastic, showing 3 well defined peaks. There are a few blips in the elevation data from his GPS unit, but overall it's pretty impressive.
I think that's about it. It's basically going to be a completely new site. Check back soon to see it, hopefully we'll have it up by October.
