This would be a nice feature to add to the geocaching, but for me there are a few changes that would be a necessity:
1. No automatic update of the coordinates of cache. make this optional. Changing the coordinates on a cache has caused far too much confusion for me between solved and unsolved. For that reason I created a separate GSAK file of solved caches.
2. Many puzzle caches solution are a word or phrase. I have one such Unknown cache. As proposed this seems to have only one option - coordinates. We need both.
3. Many have brought up the option of pasting in the solution. That would be helpful.
