Update:
And it was fixed - hence changing the review to 5 stars.

This is a simple extension that does exactly what it says it does.
You get an icon the brings you straight to the window with Google Keep Notes.

Elegant and fast :D

simple and fast. perfect

Awesome! this is best addon for google keep!

Omg I love this so much! It makes google keep so much more useful again! Hugs to the developer!

Excellent way to keep Google Keep ready for your workflow.

Nice Work!
But title is "Pinned Google Drive" not "Pinned Google Keep" in about:addons.
Except for this point, it is perfect!
