Perhaps you could consolidate all of the save modes into one page with tabs, like...
It bring up a page that shows the picture and the quality, and along the top, it has the filetypes that it can be saved under, like PNG, GIF, and JPG.
Being a graphics designer, I have to get the lowest filesize and the highest quality possible, and that involves going through several settings and comparisons to make sure I get it right, not exactly time-consuming, but something like this would be a great help.
