Skidoo was my first PmWiki skin. I designed it from scratch, specifically for note taking. I use PmWiki to capture all my work and personal notes, and wanted something that provided quick access to recent pages, projects lists, table-of-contents, and most importantly quick access to the pages used on side-bars, headers, footers, etc.
Skiddo has all that. You can quickly edit all the main page elements, to add new links. It also has tabs in the left and right columns which provide access to various pages lists, for recent edits. Not especially pretty, but very functional.
