It'd be helpful if there was a visual display on the side when selecting a document, so that I could see what I'm looking at and have the ability to rename it without completely opening it.

But the important thing is they indicate that it is free to use online, but they demand that we subscribe to make a charge, then we do not have the link to cancel

Its OK Easy to use on desktop, but on the mobile it was OK like C+ overall, but good idea It does what it should, but its a simple to use. If I had more time to use it, maybe give 120 day trial? I loved the signature and email process of the paperwork. Thats was easy. I wish we can do more in the free trial. So I can dig in more. Make the mobile experience more easier

Thank you so much for the super prompt reply! I had somehow removed the date stamp from my digital signature and I could not figure out how to get it back on. Turns out it was a pretty simple fix (doh!). Kara responded super fast to my cry for help. She provided written instructions as well as a screenshot (very helpful!). My date stamp is back on. :)
