Professional layout tools also allow the letter-spacing to grow and shrink and you can tell them to stretch or squeeze letters. Doing this is obviously very controversial but I think that allowing InDesign to stretch and squeeze letters by a percent or half a percent is visually not noticeable (at least with body text) and can noticeably reduce the number of large holes in your text, especially if the columns of your text are relatively narrow. Other word processors don’t give you that option at all.
