I don't like notifications. I've minimized the number of notifications I receive on my phone to basically: direct messages, and phone calls from my wife. I also don't like notifications on my desktop system. I've turned everything off on every system I use.
But there's one place that I visit constantly, every day, every hour, where I couldn't get rid of the tiny blue dot that indicates that something changed, someone commented, or something new has to be reviewed. And that's GitHub.
During my last vacation, I logged out of GitHub on all systems, just to avoid seeing that blue dot telling me that my colleagues at work are busy saving the world. I didn't do any programming during that time, but I still had to visit GitHub sometimes!
Anyways. The internet, of course, has a solution. Using uBlock Origin, I can remove only the tiny blue notifications indicator from my github.com. It's something like "right click >> block element >> select the blue dot".
In the uBlock settings under "My filters" there's now this entry:
! 1/15/2020 https://github.com github.com##.unread.mail-status
which solves all my problems. :D
