# Moves currently focused window from one monitor to the other.
# Designed for a system with two monitors.
# Script should be triggered using a keyboard shortcut.
# If the window is maximized it should remain maximized after being moved.
# If the window is not maximized it should retain its current size, unless
# height is too large for the destination monitor, when it will be trimmed.
