Saving and recalling window/mode layouts?

Hmm, may not help you directly, but I wanted to re-create the Anonymous modes I created when doing the initial screen layouts. I wonder if this can be expanded to save as named layouts .... anyhow I know this is not directly answering your question but maybe gives some ideas ? - here the link to my blog where I show how to "name" an anonymous mode so the system reads it back next time the application starts.
