On first blush,this is a fine tool. I have a limited number of documents. So this works great. Simple. Easy to follow. Support answered some not so obvious questions quickly and easily. Well done. I have one question or suggestion..I would like to merge a couple of my documents...but don't want to pay for a full upgrade for just two or three uses. Can you offer a "yeah we'll let you do this" one off pricing for someone like me? Would be very helpful. (I will also say I tried several of the competing products...and this was far easier to use)

it did take me awhile to figure things out because I am older, I didn't realize that I couldn't upload my documents until I subscribed to the free trial
