A few GUI questions.

Is there a way of linking the visibity of the toolbar to the node edit area. I know both can be hidden individually but if for example Im trying to get maximum viewer area and so hide the node editor, I don't see any reason to have the toolbar visible when the node editor isn't.

More than a few times I've been trying to move an asset in the timeline view just one frame but find that the control isn't fine enough. Pressing the control key doesn't appear to help. Is there a way to activate a fine control when sliding assets around in thie timeline view?

Is spline animation in the planar tracker broken?

'Right click for track spline' isn't what I had imagined, it is decribed in the manual as 'a spline containing 4x4 matrices at each keypoint'. I had assumed it was the shape defining the area that would be used to obtain tracking data. So it's not broken, the shape never could be animated with keyframes.
