I would like to propose a new link be added to each Category, utilizing the PDF technology idea found on Geocaching.com of sorts.
When viewing an individual Geocache, premium members have the option to download the cache page as a PDF document for viewing, printing and saving. This could be applied to Categories for field use.
Having a variable data page which fills in with data from the Category pages available for download from the Category itself would be an easy solution to enhance usability for the avid or new Waymarker.
In my view it should include the Category name, Icon & Grid Ref, What is it about, How to Post a Listing, Variables and How to Visit a listing.
