After reading so many threads I thought I should make it happen.

About this module:

• It adds a tab on product page
• You can add n number of internal tabs inside extra tab
• You must configure file name after installation
• e.g. Sizing Guide, sizing.html (where "Sizing Guide" is a tab title and "sizing.html" is a file name)
• If you want to have more than one file use semicolon (;) as a separator

I would appreciate your feedback.

Please tell if you found any bug.

Thanks and Enjoy!
