design for style
A target="_blank" alternative for Drupal, or saving users' content by overriding the filter tips link
In Drupal, users can accidentally lose content on node add/edit forms by clicking the "More information about formatting options" link and browsing to a new page. That's not so good.
I remember when I first started working with Drupal, one of the biggest challenges when theming was discovering what variables were available to me.
Perhaps I didn't like the formatting of the date as supplied by the default $submitted variable and wanted to see if there was a simple timestamp I could format...?
Luckily I came to learn of the get_defined_vars() PHP function which returns an array of all defined variables within the current scope.
