I love to be able to use the pdf filler app much easier and it has become very important for us in documents we need to fill out and sign and send. I would like to see some ease in the selecting the editing of a document, can the display of boxes for each section be less overlapping each other, this may be difficult to do. Sometimes when you have a saved pdf document you do updates rather than create a whole new document, we use them as templates. Right now the easiest way is to create a document in Word, save it as a Word doc and as a PDF doc. Which is okay, often, time is a factor and to quickly update a pdf file would be faster. Thanks for listening.
