Using iPhone to complete apps and send out for signature.. Had some glitches.. Wasn't able to select or choose (full access or sign only option for recipients. The screen shut down too quickly each time and 'disappeared before I could actually select.

Great. But may steps to create a PDF. Also deleting pages is not included as standard. But there are easy workarounds to this restriction. So why have this restriction?

Very useful. Would like to see a Strike-Through option where the user can highlight a section of text and select the Strike-Through option to strike through the selected text. Thanks!

Accounting Assistant This software made it easy for me to complete a single 1099-MISC that i needed and that i wasn't able to use my current software for. I was able to quickly create the document and send it out to the necessary party on a time crunch. This would not be good to use for a large amount of 1099's but, it did meet my needs.

Time saver! I have used PDFfiller for several months now and love it. It is a great tool which makes it extremely easy for me to quickly and efficiently fill out PDFs and return them to the sender. Wether it be filling out forms or signing a contract, it has saved me many many hours in the long run - and is a pleasure to use! There aren't really any cons to this plugin - it does exactly what it says it will do. However the user interface could be improved
