Removing h1 of left and right columns

[Ruud]

I want to remove the option of making h1 tags for content elements that will be in an article that is left or right column. This will not prevent the possibility of getting h1 in the asides, but it will sure help preventing. The reason is that I would ideally have only one h1 per page according to just about any seo guide. There must be some truth to this.

Is there any extension that already does this?

I created the extension. It can be found here: http://contao.org/extension-list/view/h ... tions.html
