This extension make possible to manage easly lots of bookmarks. While others browsers ignore the bookmarks sidebar, this little extension improves the experience.
I'm a early user and i never had crashes or problems.
I suggest to try it, you won't came back to the tree view.
i hope that the developer will add a function to clone the bookmarks sidebar in a tab to improve the drag and drop experience (like all in one sidebar).
