The features are great. It would be nice to have the option to combine PDF documents. I also have an issue when entering text where the text box disappears and I have to click on the document again to enter text. Aside from that, he existing features are great and I would like to see how PDFfiller can improve in the future.

It's MUCH EASIER TO USE THAN WONDERSHARE PDFelement 6! Which costs $$$$ more than PDFfiller. I could not use the Wondershare PDFelement 6 and got a refund. However if PdfFiller increases it's costs I will attempt to buy the Adobe program. It's not that I use pdf that often that I have to pay a monthly cost.

Some of the protocols are cumbersome. For instance, when you want a standard form, it makes you go through a process instead of taking you right to the form.

All PDF tools in one app
My overall satisfaction about that app is a lot, it's just great tool for everyone, for students and also employees as well, at any time people can make change in their document and send it wherever it's needed.
That's basically great app, because you can solve all document issues in one app, scanning, adding image to the document putting dates, even signature, saving as pdf, or word or excel, sending to email, printing and etc. which help users to save more time.
I remember I faced problem while logging in, actually I think to login for that kind of program is something extra.
