I highly recommend this add on. I was having trouble at first after I donated to get the pro version. The developer patiently worked with me to figure out what I had done wrong. My mistake in activating it was I entered the activation code using caps as well as lower case. You need to enter it exactly as the confirmation email shows you. No caps, spaces, etc. Now it works great. Please donate what you can. The developer has obviously put in a lot of work and provided great support. It's worth it.
