I've been wishing for a "remove formatting" button to remove all BBCode formatting in the editor. When pasting in content from a webpage or some other sources, the GUI editor often tries to convert the formatting to BBCode. I often end up stripping it all out -- sometimes requiring much effort. I think that I'd want such a feature to only remove formatting codes but not affect URL, IMG, or other similar codes. It would probably be best if it would remove codes from highlighted text only so that the user could be selective about which text should be stripped.
