Hi:

Download & open this file , I have all instruction in the comments .
This is modified to wotk for SS3 . Also there is a google custom search built in to auto search many good SS Blogs & api.silverstripe.org .
Here is the Direct link to the custom google search : http://www.google.com/cse/home?cx=010558900908239387678:vqc2gretvaq

let me know if there more website i should include in the custom search ;)

Nice idea! I spent the last months working on debug functionality. You can check out the result at https://github.com/jakr/developer_dashboard/. I followed a slightly different approach, the documentation is at https://github.com/jakr/developer_dashboard/blob/master/docs/en/index.md
