Perplexing need for this add-on 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!
