Its good for the most part - the downside is it doesnt open for me on the first try and it asks me to sign in everytime i need to print or save a doc. even though I pay for the service. Annoying that it doesnt recognize me when I use the app.

Ease of filling the forms. There is one change if you can make will be great... in date of birth column, once you click on it, you have to put the MM/DD/YYYY. If you can allow to override that and just put the year, that will be of help. In my case where my father was born in 1920 and his date of MM/DD is not known, I'm forced to fill it with incorrect information.
