I was tasked with maintaining a Drupal website that had 44 views. The template.php file for the theme was unwieldy. I spun off all the views template code into another file for ease of maintenance, but it was still 1333 lines1 weighing in at 36.5kb! [1] Just four more lines and it could have been elite!
The quantity of views certainly wasn't pretty, and when I had to add in another view, I decided that enough was enough. It was time to clean it up and develop a system to help keep the views under control.
