On next release I'll be adding html minify. This will remove unnecessary spaces and lines which are just the waste for bandwidth. The less size the file it loads faster. Also it saves bandwidth of the visitor. I have already applied to my site today. If you view the source code of this page you will understand what i am talking about.
Google's pages are compact, so probably it will like this idea and also other search engines. But of course this feature will be optional, which you can turn on/off for entire size and also set different on/off option for some controllers/pages.
