Used to be good.

This was a very good app when I first got it about two years ago. It undergoes constant updates on the basis it is improving and eliminating bugs. However, in the new update where they changed the UI, the program has major bugs, especially in the PC version, and my Mac version crashes. It looks like the new UI is designed to sell you a "free" fax number and the rest of the program has degraded.
