I'm really liking the beta Premium Advanced Search at Geocaching.com (#Geocaching +GoGeocaching
A couple comments:
1. Pocket Query (#PocketQuery) - There needs to be a Create A Pocket Query button. Otherwise this super cool searching is all for naught.
2. Toggle - Once you click "Map these results" you seem to be stuck on the map unless you click on a cache. it'd be nice to be able to toggle back to your search to possibly fine tune it more. the radius would be common to want to adjust.
3. Filter Options - They rock. some are obvious (fav points, radius). But some options some were a pleasant surprise: exclude finds by specific users, corrected coords, & personal note.
