You can use the HTML Purifier plugin and allow any other tag also:

It should do the trick, I’m using it & it works like a charm…!
That was fast…!!
@finalwebsites: I’m using the allow-images plugin. Of course I just have to do the same thing for headings. Much lighter than HTML purifier. Thanks mate.
@Gautam: Great plugin anyway. Thanks for sharing.
Cheers.
And… [resolved]
Look awesome…! Getting closer of the wordpress.org theme, unity… I like it !
