Small update for the poser, you can now select the bones from a list via double click (sorry, single click doesn't work for some shitty UI reason) and then alter the selected bone via the 3 sliders. You should press Start Posing before you do however. I figured you wanted to know.
It also allows you to change all Bento bones. Yup, all 133 bones are now changeable.
Next up: Saving to XML. Editing collision volumes. Export to BVH (possibly). UI improvements. Usability improvements (maybe having the rotation axis circles like in Edit mode).
