This program has allowed us to reduce the amount of time it was taking to complete our main work task by at least 50%. The only significant improvement that would increase our experience would be the ability to rotate any specific text input by 90 degrees.

Good layout and simple to understand Good layout and simple to understand. However, while editing I realised that it does change the original size of the item when it is converted the format.

This software has solved many problems for a few clients, well done. Being able to host the forms online for anyone to fill out, which is something that I couldn't find with any other software. No way to remove the flow of fields, you are just able to move the order around, which is very annoying as well.
