Personally, I like having the embedded browser as it makes reading the news more convenient in one location rather than skipping back and forth between an external browser and QuiteRSS, so thank you!
That being said, it would be nicer to hide the browser and make the News List use the full screen. When clicking on a News title, it would then open the article in the browser that would pop out over the news list area. To go back to viewing the news list you could just click the 'x' on the pop out or click anywhere outside of the pop out. I suppose for those that don't like the embedded browser, when they click on a title it would just open in an external browser by default. See feedly.com newsreader for an example of how the pop out works.
I think this would satisfy those who want the browser hidden as well as making better use of screen space.
