Almost perfect Rated 5 out of 5 stars

Positive:
- does exactly what it should
- integrates very neatly into the browser
- expanded folders stay expanded when creating a new bookmark

negative:
- when you don't select a fold and click outside the menu it closes but the bookmark is created in unsorted bookmarks rather than being discarded. if this is fixed i'll give 5 stars.

EDIT:
Although i don't agree with the implementation, as there is a way to cancel the bookmark creation i have to give 5 stars ;)

This review is for a previous version of the add-on (1.2.9). 

Hey Sebastian,

That is as intended. You created a bookmark but didn't sort it, so it goes to the "unsorted" folder(Unless you changed the default folder).

If you want to cancel your bookmark, you can press the escape key instead.

Thanks for the feedback though.
