Directions to find the form to be edited could be more simple and spelled out. Through trial and error, I was able to edit the form to my satisfaction. Thanks.

This little program is life-changing. This little program is life-changing. Needing to continuously reproduce docs from old paperwork and (business) historical documents is insanely time consuming. Retyping, reformatting you name it. Sometimes OCR software doesn't cut it. With this program, I've cut my frustration time by 90%. My production time is a breeze. The remaining 10% is my learning curve, but I"m figuring out more as I go, and when stuck? Kara is in chat to figure it and me out. Done. Well worth the subscription. Thank you!
