This so called 'feature' is very annoying. I am totally baffled why it even exists, and why Opera allows it to be 'hard-coded'.

Perhaps I am just not seeing the usefulness for a list of uncompromisable data. Can someone please explain how this feature can be useful?

Thanks a bunch I will try that work around.

I uncheck Mailing Lists, but every time it reopens it is checked again. My Mailing Lists are hundreds of listings and I don't care to use them. How do I get rid of them from the side Panel?
