V1.0.1 with an indicator overlay for active/inactive

Use <arg>-status_indicator=size in pixel in config before the first <focus>.
e.g. <arg>-status_indicator=20 # indicator circle with 20 pixel diameter

changes color if to red if key listener is inactive and green if active ^^

• left click to drag indicator to new position

• right click opens a context menu to separately close the overlay - cli program is still running.

• indicator should close if cli program will be closed

• indicator always stays on top - not tested with full screen programs yet
