WordPress filters grouping

Provided the list of WordPress filters in here, created some time ago. In fact the list is not grouped. How would you group all WordPress filters?

In fact on the following page http://codex.wordpress.org/Plugin_API/Filter_Reference I found the answer:

• 1 Post, Page, and Attachment (Upload) Filters
• 2 Comment, Trackback, and Ping Filters
• 3 Category and Term Filters
• 4 Link Filters
• 5 Date and Time Filters
• 6 Author and User Filters
• 7 Blogroll Filters
• 8 Blog Information and Option Filters
• 9 General Text Filters
• 10 Administrative Filters
• 11 Rich Text Editor Filters
• 12 Template Filters
• 13 Registration & Login Filters
• 14 Redirect/Rewrite Filters
• 15 WP_Query Filters
• 16 Media Filters
• 17 Advanced WordPress Filters
• 18 Widgets
• 19 Admin Bar

Not all filters are covered but the grouping is awe.
