On a whim, I installed the latest nightly of Optimoz Mouse Gestures on TB .3 and a lot of the functionality appears to work within the message pane. The only thing that I've tried that doesn't work consistently is rocker gestures (sometimes the context menu comes up) and Open Links in new Window/Tabs don't work, but that seems like functionality assuming you're using the Mozilla suite.
I know that this probably isn't supported officially, but it's cool to see that it's working for the most part and am looking forward to more functionality in the future!
Thanks optimoz team!
