Enhancecv is pretty easy to use and the user experience is also very good. All in all I like the tool very much and don't have anything that I can think of that I would change on the technical site. I would recommend to add some more Designs or leave the user more freedom to use the great elements you already have. Maybe a Sandbox mode where you can choose your own layout with elements from your different templates. For me personal I would love to have a block where I can set the date, location and upload a jpeg of my signature. I know that this is not really common in most parts of the World but it's a bit fiddly to add that. Keep up the very good work!
