I'm just going to add myself to the line of unsatisfied customers. The new search is functionally inferior to the old one. Especially the limitation of 1000 caches is ridiculous – I can't even see all the caches I found. I really hate it when functions are taken away from me and my comfort is lowered – as a paying customer, I expect improvement of the services, not the opposite.
Also, the change of Basic Members not being able to see other members finds is very inconvenient for me. I often cache with my girlfriend, who is not Premium Member and we don't want both of us logging our finds during the trip – the best way to work until now was that I logged all the caches and she logged them afterwards based on my finds. If you don't want to enable this globally, please consider at least allowing seeing all of your friends finds. Otherwise, this change will really negatively impact my geocaching experience.
