Totally Confused about Upfront!

Ok, so while waitng to get my question answered was going through the forum and I think I understand but not sure. The upfront theme is only a builder you are suppose to edit it in the page editor on wp are on upfront? Upfront is just a template builder but yet I do not see any of the edits I did on upfront on the page editor in WP. The theme I was consistantly using before coming to WPMU was a vada and their fusion builder was awesome had a way to save templates and you can visually see edits as you are doing them but with ease there were problems like if you didnt use a CDN sites were supper slow so with ease comes problems which I understand but I thought Upfront was the answer the ease of drag and drop but I am learning that is not true. Am I correct?
