Recently I had the need to display the currently logged in user's name in the main menu region. The requirement was so simple, for non-logged in users the site should just show the main menu, but for logged in users it must display their name as the first item in the main menu.
Lately I have been working on a potential Drupal 6 project that needs displaying information in a formatted table structure. Needless to say I have been using a lot of pager_query() and theme_table(). Yes, I do understand the benefits of hook_views_data() but this is a different case.
One thing I found to be annoying about theme_table() is it's default behavior of adding sticky table header and not having an argument that can be passed to disable it when needed as introduced in D7 http://drupal.org/node/224333#sticky_headers
