I really like the pictures on the download page
I know it's still a work-in-progress, just thought I'd give a suggestion or two. My first thing I noticed was the dropdown zone list, very nice, and organized well. Maybe could have a page that you could go to, and find a zone easier. IE, using built-in browser search and just having a bigger space to view.
Also, with the POIs, maybe just have a default page for them, so that you wouldn't have to goto advanced search and just leave it blank to start looking through the zones? I dunno, hehe. I'll stop rambling now.
Great work!
