Short answer
The Humble icon turns green when you have a note on this page or this site, or a task linked to this page. Purple means there is nothing yet.
What the colours mean
See it without pinning
Turn on Show the Humble bookmark on web pages in My profile. A small Humble tab then sits on the right edge of every page and turns green in the same way.
Questions
Why isn't it green on a page I saved?
Check the note is linked to that page. Notes you add from the sidebar with + next to This page are linked for you.
Do contacts turn it green?
No. Only notes and tasks do.
How does Humble know the site?
It looks at the web address. On LinkedIn, each person or company page counts on its own. Each AI chat counts on its own too.
