Can I move the Voice button to a different monitor?

Move the button by clicking on the grab icon (six dots) in the border tail and dragging the button. The next time you close and re-launch Voice, the button will open in the last place you left it.

Keep in mind that if you're using multiple monitors you can move the button to a secondary monitor and the button will stay where you put it until you sign out or close the application. After you sign out or close the application, the button will open on the primary monitor when you sign back in.
