01 · The problem
The site almost works the way you want. A few lines of script would fix it, if you had somewhere to keep them.
github.com, default layout
GitHub Full-Width Code · https://github.com/*
02How it works
Add it, run it, know it ran
- 1
Add a ready-made script
33 scripts in 7 categories, searchable by name, description or site. “github” finds GitHub Full-Width Code.
- 2
See what ran on this page
This page lists the scripts that match the open tab. A new script waits for a reload, then reports when it ran and how long its setup took.
- 3
Pause everything at once
One switch stops scripts on new page loads. Pages already open keep the copy that ran until you reload, and the panel says so.
