Virtual keyboard's y position can't go low enough + saber width problems

Hello,

So I tried out the demo to make sure I suits my needs before buying. I have encountered two major limitations though which makes it impossible for me to use it right now.

My setup is very uncommon : I physically align my keyboard with a big wall-mounted tv screen, and show SeeMusic fullscreen on that TV. I want an animation while I play.

Two problems :

1) I have to align the saber almost with the bottom of the screen to match the top of my physical keyboard, but that's currently impossible because I can't go low enough with the "y" position. "0" isn't the bottom of the screen...

2) When scaling down, the saber scales with it and has boundaries on the side. I need it to remain full-width, and to only scale the virtual keyboard down.

Is there a solution to this that I missed or in a future version ?

Thanks !
