Just started using the program today. Easy so far. A little problem with the aligment of fields. It would have been great to use the "tab" key to toggle between fields.

I was pleased to find the AIR realty forms on your site. We're trying to sublet our space in a commercial building and our landlord insisted on using the AIR forms

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.

Used the product a few times (PDF editor) and really liked it but disn't use it enough to warrant purchase. I forgot to cancel the free trial and was charged the annual fee a few weeks later. The company immediately refunded me when I requested it, and did so without question or issue.
