In my older review I gave 5 stars to application, but after author decided to make money and released "semi-free" version that is crippled to unusable state, he lost two stars from me. He took advantage on people who helped him debug and improve application because it was free.
Most of the reviews here are posted while actually free versions were available.
Try to find version 6.8. That is the last actually free, fully functional version. Not polished as current version but more than good enough.
