since this was the emulation of a mouse click and hold I would say: yes.
Does that mean you'd have to do it with the actual space bar of a keyboard or there a way to do movement turns just using the mouse?
Either way I am sold. Seriously considering making a contribution. Its a shame the deadline is Wednesday
the actual spacebar. The workings of MT haven't changed for this cool-tool, so MT still expects a left or right mouse click and a pressed spacebar, the cool-tool however emulates the right mouse click by 'touch and hold (and don't move)' and the left mouse click and drag by 'touch and drag' (at least that's my assumption). Unless they build in a 'press spacebar' emulation in their cool-tool MT will still require an actual space bar being pressed during move (preferably one that's actually connected to the pc that runs the MT instance) in order to execute that command.
