My only two complaints are the price and the fact that if you only want one page out of a file with a lot of pages... it seems the only way to "quickly" do it is to go in and individually delete each unwanted page. Otherwise, it does most of what I want.
Anonymous Customer
Sometimes its a little difficult to navigate around especially for making an application, but once its set it up it works well. Ive noticed 2nd pages are difficult for customers to see and fill out. Wish there was something that would prompt them to go to it.

What do you dislike?
I can't figure out how to combine 2 PDF'S and merge them together so I use a different program for that.
