Rated 5 out of 5 stars

Worked really well when I used it originally. Most of the places bugs have since been fixed, except for
Bug 430580 – User defined Saved Search should be editable.
Bug 409704 – copied tags containers do not live update correctly.
Bug 418141 – The Library should persist expanded details pane status

This review is for a previous version of the add-on (6.4).
