Rated 5 out of 5 stars

I'll never understand why TBird implements true previous/next functionality ('F' and 'B' keys) but provides no client buttons for it, bizarre. I'll be waiting for the 5.0 release unless I get accustomed to the F/B method.
EDIT: I just tried the ACR method and not only is it working for me but I see the button icons too somehow! (WinXP SP3/TB5) Kewl!

I don't understand why TBird users still have to install an add-on for this functionality. Be that as it may, this add-on gets the job done in TBird 3.1 but on Ubuntu 10.04 the icons are incorrect. Real Previous is the Archive icon and Real Next displays the Compact icon. I tried changing to default Humanity icon set but same result. Icons look fine on WinXP and in both OSes the buttons work as expected. 5-star when icon issue resolved. Thanks!
