Just noticed there is a new blog post that addresses my last topic here at http://kingkoo-salesforce.blogspot.com/2013/09/winter-2014-give-me-back-my-code.html on the code coverage since Winter 14 was introduced.
I urge you to go take a good look.
By now I am used to going to Eclipse or Developer Console to view the code coverage. I still missed the fact I cannot see the information from my Apex Class page, but I think I am slowly understanding the reason behind it.
This blog was written by Josh Kaplan - he is the Product Manager for Apex at Salesforce.com

Enjoy!
