PDF when u can't PDF Overall, this is a great software. I use often , and find it very helpful. I mostly enjoy being able to use this software on my cell phone, and then able to complete PDF's when normally this would not be possible. I love this software, but it is sometimes difficult to use. The features are not as basic as I'd like.
