EnhanCV has the cleanest and most attractive resume templates in a rapidly saturated resume / template service market. While the UI is easy to use but there's definitely bugs in the "Resume Tailoring" section which discourages any repeated use of it. In addition the front end UI is very limited in that it won't allow custom fields. Also the skills field cannot receive any nesting/organization, so it ends up looking like a hot mess of keywords that cannot even be easily reorganized. The lack of flexibility of reordering/structuring skills is profusely frustrating.
