Well, the bottom line is that they can be hidden by editing the xml, which isn't too difficult and there are plenty of people who can help.
The trouble is, if we change something that has always been there, many people will demand that we put it straight back.
That's cool. I'd looked into this before and thought it was hardcoded somewhere as I couldn't find an .xml for it, but if there is one that I can edit that's great. Could you tell me which file it is please?
