What would be nice if someone would build (or has) a combo text editor/page layout suite where the text editior is light weight like Text Wrangler, so you do all your typing there. Then when you are ready to do layout and formatting, fire up a separate utility app that reads in your document, and you can visually layout and format a document, producing a second version with the layout metadata, leaving the original as plain text.

When will companies learn it's time to break out functionality into utility apps. We don't use 90% of the stuff they shove in there!
