Once I became familiar with the input it was pretty easy to use. However trying to Print was difficult. The on-line help didn't suggest using the DONE button!

There are things I still can't figure but overall, I am getting the hang of it and it seems fine. It takes a while to go between pages but that could be on my end.

I really like working with the filler although there could be better control in the editing. I believe it could be more intuitive as to the fields which are potentially fillable and place the cursor within those lines automatically. It is fussy to try to line it all up.
