Best WordPress plugin for on-page editing?

I am looking for a WordPress plugin to edit a page while looking at the final version of it. I need the ability to click and edit any element on a page. Also be able to duplicate/delete/move elements. For instance, clicking an image would bring up a menu allowing me to change the image, delete it, move it, duplicate it, etc. Does anyone know if a solution like this, or something similar, exists?

Thanks!
