Turn off the Close windows when quitting an app option in the General pane, so that SkookumLogger will open your most-recently-open log at startup.
Turn on the Use F1, F2, etc. keys as standard function keys option in the Keyboard tab in the Keyboard pane, so that you don’t need to hold the fn key while tapping a function key to transmit SkookumLogger messages. Also review the settings in the Shortcuts tab if you discover a collision with default SkookumLogger shortcuts.
If you use two displays with SkookumLogger, turn off the Displays have separate spaces option in the Mission Control pane, so that open windows will be positioned as you left them across SkookumLogger restarts.
