I would find it really useful if a cache owner had a way of linking caches in a series with a way of navigating to the next one from one cache page to another without having to go through a list page or a map view to pick the next one. The Lost River Fleet series has one that the original owner set up as part of the description (see here for an example: http://coord.info/GC2PZVG) but I would like to see this as an optional feature on all listings. It would make planning and logging a series much easier. What does anyone think?
