Coin-Ticker Alarm Function Suggestion

This alongside any other chrome extensions used to track the price of cryptocurrencies doesn't have or its very rare for them to have a simple but incredibly useful feature. The feature i'm talking about is alerting the user when a cryptocurrency hits a certain price point with for example a simple beeping noise or opening a pop-out window.

Proposed Solution/Suggestion:

My suggestion is very simple and it involves adding a bell next to a crypto. When checked, it will notify you when there is a sudden change in price or when given crypto reaches a certain price point, that could be set in the settings.

Benefits Comming From Adding This Feature:
In my opinion this would be incredibly useful, as very often users are doing something else on their computers like watching a movie or reading an article and don't have the time or ability to check the price due to being focused on something different than a price chart. They'd still like to be notified when there is a sudden drop or peak in price. Here's an example:

Conclusion:
This is an uncomplicated function that is unquestionably worth adding, as some users would still like to be notified of a sudden change in price or simply about their cryptocurrency of choice hitting a certain price point, without the need to do anything at all.
