"More Options..." button for posting replies

At the bottom of the page, when viewing a thread, there's a text box for typing a message to post to that thread, immediately below which are buttons for "Post Reply," "Upload a File," and "More Options...." Clicking on the last of these takes you to a new page that really only offers two additional options: a "Preview" button and check boxes for "Watch this thread..." and "and receive email notifications." Is there any reason why these "more" options couldn't just appear on the original page? That is, the "Preview" button could just replace the "More Options..." button -- thereby not taking up any additional space or adding any clutter -- and the check-box options would just appear below the three buttons.

I suggest this for two reasons. First, I almost always "Preview" my posts before hitting "Post Reply" -- to proofread it and to catch any formatting problems (for example, text appearing next to an image when I wanted it to appear below the image) -- and having to go through "More Options..." means an extra step. Granted this is only a trivial amount of extra work/time, but I'd rather not have to do it if I didn't have to. Second, and more important, I wish others would use the "Preview" function more often, for the same reasons I do, and maybe having the "Preview" button right there (rather than hidden under "More Options...") might encourage more people to do so.
