Its amazing, nice implementation. Here are some good-meant critiques:

Please add..

- rotation marks at the shoulders (I cant get the girl her hand behind her head)

- a button to switch presntation rotation on/off (its now too hard to get in the right editing mode

- dont zoom in when moving the mouse up and down, use a shift+... combination

- add x/y/z axis camera constraints. sometimes its not very easy too find the right cam angle to edit. Perhaps you add a 4 window system (top/side/front/unlimited)

- do the planes have different meanings or not? I dont like truspace itself, but here it would be cool (as long as you have only one editing window that is unrestricted) to add a movement by plane selection (planes represting the xy/xz/yz planes, drag and drop to move the bipe).

- let the user select an editing node by option and let the camera circle around it (or add an offset feature)

- add a timeline feature to save poses and insert/delete/interpolate between them
