Basically good, needs more features Rated 4 out of 5 stars

Works well enough but it's kind of lacking in features, and it's annoying that it includes app-tabs in the bookmarks. Desirable features for me would be an option to not include app-tabs, to customize the format of the names it gives the folders (not just the prefix, but for instance with a format string), and to optionally launch a dialog to give the folder a different name (for instance, if you hold ctrl when you click the button).

Also, the button looks too much like the normal favorite button, it would be better if it was different.
