Change / remove checkout process

Hello.
First of all, awesome plugin, very easy to use for absolute beginners like me. Job well done guys!
But where is one thing that I would like to change is checkout process. I am planning digital products, which could be downloaded for FREE, so I don’t really want to have checkout process at all ( I want to remove it) but I want to leave grid appearance for my products with downlaod button. Is thre any way to do it?
Thank you 🙂
