Monitor any page for element changes (based on certain query parameters) and pop an alert if a change is detected. Shows a timer on the bottom that you can pause onclick.

Extremely basic and experimental at the moment, use at your own risk.

Example use:

Monitor for price changes (not just drops) at Amazon:https://www.amazon.com/dp/B09NM56KJM?change_agent_el=.a-pricehttps://www.amazon.com/dp/B09NM56KJM?change_agent_el=.a-price&change_agent_time=60 (reload every hour instead of every 15 minutes)
