The ease of use, the ability to do all of your dental image processing without the need to have the expensive software installed on your computer. Not much. Just keep it up and running. It will run slow at times. Maybe make a new version. Have more features. Have less of a learning curve. Make it easier to use and have more functions. I have had to go back and forth between software applications. This software has been a help with all of that. It has been very helpful in the way that you can do all of your image processing without having to have the expensive software installed on your computer.
