4 Stars for the great idea!

Missing two very important features that are preventing me from using it:

1. Having a badge to let me know if the current page has a bookmark, like telling me the number of bookmarks on the current page.

2. On pages that have a bookmark on a location that is still not loaded, that require scrolling to bottom in order to load the rest of the page (like YT for example): have some kind of an indication from the extension to tell me that I still did not reach the actual bookmark location.

Finally, the extension does not say how it links bookmarks to pages; does it use the domain only? does it use the full URL (including tracking data in the URL)?

Thank you claudiabdm! It's works 100% for me. X/Twitter was driving me insane. Thanks again!

Perhaps you could add a dark theme to the main view box? Right now it's only possible to view the marks with a light theme - a dark theme alternative would be much appreciated.

Also, it'd be nice if there are shortcuts like a hotkey config for the first mark created or something added to the add-on too.

But overall, it's a good add-on! It does exactly what it says on the description.

Hi ! :)
its a good job!
is it possible to attach marks to the left sidebar? Or attach marks to scrollbar with its names?
that would be awesome! and 5 stars.^)

UPD:
Perhaps you could add to the settings an option to choose where to display it -- in the sidebar or on the scroll bars.
