Hi! I didn't find suggestion like this, so.. On macOs there is good app https://eternalstorms.at/ScreenFloat that have feature like this, autohide application window on mouseover, and show it again when mouse leave application area. It's is very very useful, when you work on one monitor and you need to click some button under refs or tweak some sliders. I'm surprised that PureRef doesn't have that handy option. It would be good to implement it if possible. Thanks! :)
