thanks again. it's not actually an app (at this time), it's purely web based. and for the moment, it's being made to help me out when i'm there, but I'm happy to share it.
I would actually love it if people could start testing the GPS functionality (sorting by Near). I only have TDL working right now, but should have TDS soon. I'm just wondering how well it works.
If you move around, refreshing should update your location. it won't refresh on its own, though I'm planning on just forcing one every 5 mins or so.
