Zoom editorThis is something I blatantly "borrowed" from WordPress. When you write a long post, I find the relatively small post editor slightly annoying and this is where the zoom feature enters the game. Basically, you press a button and get an expanded editor that covers your entire browser window. The tool bar and smiley selector will remain on top of the editor, but everything else will be gone, allowing you to fully focus on the post content. WordPress calls that feature "distraction free writing" and that pretty much nails it. It's useful for people who often post long articles, like tutorials or reviews. See attached screen shot how it looks.It works with both the basic and the WYSIWYG editor and should work in all modern browsers, including IE8 (no, that's not a modern browser, but it works anyway).
