Using the taxonomy view to change how taxonomy listings are displayed is rather nifty. However, I found myself being asked by a client to make sure the page title (ie: the taxonomy term as set by the argument) was properly title-cased. That issue comes up from time to time on the #drupal-support IRC channel, so I suspected it would be easy, as many people had done this.
When working on a Drupal site for a client earlier today I had an odd problem.
The client wanted a page that lists downloadable files and has a little blurb about the downloads at the top, so I duly created a view that lists all published nodes of type 'Download' and sticks some HTML at the top.
