It offers smart input, supports pause and resume and can run multiple

You can minimize to tray and control from the tray, have the window  
stay-on-top, go full screen, pop-up, close or shutdown computer when  
expired, add sound notifications, keep computer awake, loop timer, loop  
sound, open saved timers on startup and more."
