- Mouse tracking co-ordinates are set to the center and extent of your main monitor by default, but you can move them outside of that. Co-ordinates are still relative to the main monitor to make it consistent in case you want to spread it over all of them. If you have "show layer bounds" on, move your RahiTuber window into the desired monitor and you'll see a little crosshair appear at whatever "neutral position" you've set.
- To make states exclusive like that, the only real way is to tell the state to hide all the other mouth positions you don't want showing up. You can either hide the specific layers, or hide a folder containing them. You can also make use of the "hide with parent" option in the motion parent setting. As long as you use "Toggle" or "while held", this will still be reverted when you deactivate the state.
- I have been thinking of adding more than visibility to the states for a while, but it'll require an extensive rework. Sorry, i haven't got there yet!
