File Cache -the 'Overwrite if already exists' option could be removed. Instead, if someone tries to upload an image with the same name, it could say something to that effect. At the moment, you have to remember to press that otherwise it will error. It would also be useful if you could search the file cache for a specific image if you know the name of the image, rather than going through each page to find it.
Preview before check in -it would be cool to have some sort of preview generator when you make a change on the site so you could preview it before you check in & save.
