Pagegories in the sidebar
Just installed [Brian Piltin's Pagegories sidebar widget][1]. As the name suggests, it combines your wordpress pages and categories into one list, pages first. I don’t have a lot of categories any more, so it looks quite good. Another option could be to use the [Page Links To plugin][2] (which I also have installed) and make a page than links to the category listing, but this is automatic. I like it.
