I hope you guys are reading the very valid explanation from Neeraj below. This is clearly a complex problem to solve, since everyone works differently and has different needs ranging from "always the same" to "different for every project" (especially web designers). Seems to me the solution of creating your own master document is a pretty good one — easy and completely customizeable. Or paying attention to the units as you create the document.
