You can pay for Gmail, if you want to. Paying will remove the ads. Paying won't cause Google to halt all changes to the user interface forever. I expect you will have a very hard time finding any actively-maintained web service that does not periodically change parts of the user interface to better serve the majority of their audience.If you want a bookmarkable full-screen compose page, that is still available. Go to http://mail.google.com/?ui=html , then click compose, and bookmark that page.
