I don't care what you say in the other reviews "it was the original purpose of the plugin"...bull. I bought one of your plugins before for one of my clients, and in that one, we had to pay to GET the paypal feature on it. And now? we dont need the paypal feature for one of your products, yet you are going to make us pay to not have it.
This plugin was pretty much perfect, and honestly you would have had me sold on having to pay to access custom forms and using it as a widget. I was about 5 minutes away from clicking the "buy" button your premium version, until I looked closer and realized you're actually making people pay to remove something that makes the form useless if they don't want their users to have to pay to book.
Making people pay for extra features = acceptable.
Making people pay to remove "features" that render the form useless unless otherwise paid for = low and incredibly cheap and honestly should not be allowed on the wordpress free plugins area.
