Terrible add-on. Requires regular "donations" to keep active and continue access to "Pro" features, which barely work half the time. Developer's response is always the same..."Sorry, I recently made changes to the software/server/payment tracker, etc. so YOU have to donate more to regain access to the Pro features you already had." I have already paid...err "donated"...twice. I won't be wasting money on this add-on a third time.
