At the moment, heading tags in the comments and widgets sections are H3 tags. I have noticed that the K2 theme is using H4 tags on these headings. I understand that, from an SEO standpoint, one might want to "tone down" the importance of these headings, because they do not contain any keywords. However, from an accessibility standpoint, I believe these headings should be H2 tags.
Therefore, it would be nice to have a filter that allows everyone to set the heading tag they want for all the heading tags located outside of the post's content (I have identified comments and widgets sections, I may have forgotten something?). It would even be nice to be able to completely control the tag, for example completely removing it or replacing with a simple P tag.
What do you think?
