Getting rid of the CAPTCHA is easy enough, but again, why add it if I don't request it.
I appreciate your logging the feature request. On that note, if CSS presentation is necessary to keep everything tight with the new extension that is acceptable to me although I greatly prefer tables for an admin page.
The bigger issue is adding elements that are not requested and in many cases, not needed. I added the suggestion to that section of your website this morning and within the hour, 2 people agreed, so I am not alone.
