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.

much better than trying to fill out some of these forms by hand or create a form from image using something like Adobe acrobat. Only problem was you should probaby do better quality control on the forms provided. I found your Chapter 7 petition package to be unusable (all or most of the checkboxes use the same variable i.e., check one and you check them all.
