refined-github
:octocat: Browser extension that simplifies the GitHub interface and adds useful features
The refined github extension[0] has some defaults that make the default view a little more tolerable. Past that I can personally recommend Renovate, which supports far more ecosystems and customisation options (like auto merging).

Browsers' Print to PDF feature would work too. The "system" is exactly as reliable as its operator. No reminders included, but I don't want my computer beeping at me (and maybe you don't want really want that either).
