Google MyMaps

I've really been digging the new MyMaps feature of Google Maps. I even started working on a MyMap version of my university. However, I have a few suggestions/requests that would make this product even more useful for such a large and complicated area.

• Allow showing and hiding "overlays" based on the same color. Also, allow a key for what each colored area means. (Residence Halls, Academic Buildings, Parking Lots, etc.)
  
• Allow showing all areas and points of interest at once and not just those in the order they were created. Possibly allow sorting of the items allowing non-linear creation. (For instance, all buildings should be shown with their labels all of the time when the buildings overlay is shown)
  
• In their blog post, Google indicates making your map public includes it in the search results, but that doesn't appear to be happening at present. (For instance search for "googleplex building 43" which is clearly marked on their example map of the googleplex. Also searching for "Clemson Crew Boathouse" doesn't return my campus map or this one.

I think this product has a lot of potential and makes it easy to get directions for places that don't necessarily have physical addresses, like the boathouse, but I'd like to see a little more functionality for "power cartographers".
