This is still brainstorming for now.
List all wishes and make a proper feature request on http://tracker.clearfoundation.com And document workarounds for now
- template error 500 pages with actionable info (if mod_security)
- template error 404 page which looks like the rest of the site and sends URL keywords to a suggested search
- Tighter integration with Apache's >htaccess (error messages, etc.)
