- Document load speeds need to be increased
- Cannot send multiple documents for signature in one shot
- Add audio feature to attach custom audio messages to documents
- Integration with Google docs for collaboration
- The listing feature with check boxes is old-fashioned. Use icons based on file type.

I had some trouble learning to use it and directions aren't consistent. Your Help area tends to be more sales pitch on what can be done in a field with no directions. I'm very grateful for availability of the service though I'll drop it once I have my house sold in a few months

Easy PDF
PDF filler is undoubtedly among the best software I have used for manipulating PDF documents. Easy to use, it offers many features and is less expensive than other software competitors. The only real flaw in my opinion is the lack of clarity about the free trial. The user can modify his document and only when downloading it he is asked to register with a payment method. This can be confusing and irritating if you don't know it beforehand.
easy to use
accessible from anywhere
includes many features
there are often problems with payments
there is no clarity on the 30-day free trial
