It’s a good idea to test developmental changes in a protected environment where you know they won’t effect anything that’s mission critical. Typically this is simple to do as you can just edit the files on your local machine before uploading them. Making a test bed for WordPress, however, is a bit more difficult due to the nature of dynamic page generation.
Using some simple PHP and the functionality that’s already built into WordPress, you can easily control what appears on different page types without having to create multiple templates.
Code Viewer is a WordPress plugin that pulls source code from an external file and displays it, optionally adding a link to download the code directly. The plugin displays the code with proper indentation, line numbers, and long-line wrapping.
Optimal Title is a WordPress plugin that mirrors the function of wp_title() exactly, but moves the position of the 'separator' to after the title rather than before.
