Non-nestable tags are fairly trivial to modify with normal search and replace tools. My main goal was to provide something for those areas where regex couldn't be trusted--the tags that got me in trouble when replacing/changing/deleting.
I'll keep it in mind, but I'm not really interested in creating something where any tag can be changed to any other tag. That would likely get me
back in trouble again.
Find: <p class="ct">(.*?)</p>
Replace: <h2>\1</h2>
