 # Potential future improvements
 
-- Better configuration: command line parameters to customize the script on run, and a config file to provide your own defaults.
 - Stealth mode: hide the tray icon and disable tooltips on lock, making it slightly more difficult to bypass the script.
 - Temporary password: change the password at run time to avoid using the one that is readable in the script itself.
-- Lock the mouse: lock the mouse, keyboard, or both.
 - Unlock timer: automatically unlock after a period of time.
 - Inactivity lock: automatically lock after a period of inactivity.
 - Scheduled lock: automatically lock and unlock on a schedule.
