Would you consider making a Chrome extension as well? I find the idea of only showing three suggested videos quite unique and genius.

Most other browser extensions dedicated to make YouTube distraction-free only let us either show all suggested videos or remove all suggested videos, with no middle-ground. The concept of middle-ground is quite good, especially for people who don't want to be distracted by recommendation flood but also would not like to go to the extreme of removing them all.

That being said, if you don't use Chrome much and feel reluctant to implement an extension not heavily used by yourself, I would understand and we could close this issue.
