Does what it says on the tin - thank you John. Not sure why it's not working for some - I have elected to change the header not the database.

Any chance you will be extending it to change other header items eg in-reply-to and threadindex? I can't move my desktop TB to latest version until I find a good replacement for HeaderToolsLite
