Such a great addon! <3
I have few suggestions, if I may.

It would be great if tabs that have notes could have a button near the close-tab button to quickly show the note.

Regarding the banner in the top-right corner of pages that have notes, it would be awesome if clicking it could also open the note.

Lastly, having a “Add note” option on right-clicking a tab would be much easier than opening the extension every time.

Thanks for considering!
