I've been switching back and forth between the redactor editor and the offering from @cclaerhout , the tinymce plugin, and although I like the simplicity (and compatibility) of redactor, I miss the full-screen mode that tinymce offers. I'd be happy with a vertically expanding editing window or a full-screen mode. I know the thing expands when you paste in a bunch of text, but writers often like to see a canvas that will fit their work before pasting it in. Expandable or full-screen works for that. How hard would that be?
