- Cool idea - recommend to try, at least. Looks like it saves some resources on my mac, including battery and internet traffic in roaming. And my mac stopped warming, finally. It used to warm up when i have more than 3-4 tabs open in Chrome (damn chrome). Well done, author.

- Stops unused tabs from hogging RAM, speeds up Chrome, and doesn’t spy on you. Fully customizable and open-source. 10/10, would recommend!

- Suspend Time doesn't work. Tab shuts down shortly after you leave it, regardless of time. At least YT behaves this way.
