Easiest way to add an additional tab to a product?

[pghvideo]

Whats the easiest way to add an additional product tab to a product, I sell electronics so I need a tab that says "Specifications" I've tried some plugins and they don't seem to be uniform with the theme or seem spotty..

See the attached picture so you get the idea as to what I'm talking about.

Hello.

Generally , you can add specifications as attributes and for each attribute you create make setting "Visible on Product View Page on Front-end" to Yes.  

After that at front-en new tab Additional Information will appear for products with that attribute(s) -

I'm looking more for a text box to paste the product specs into vs having to create attributes for each field
