When I click in the Orion Address Bar, a huge drop-down appears, showing the content of the Start Page. (Favorites, Frequently Visited, and Reading List.) I get why it does that, and I'm sure it's useful for some people, but for me it's a strict net negative: I find it distracting every time, and I have never once used it.
So I'd appreciate a Setting that allows me to turn that off. It's a minor thing, but I think I'd be happier simply not seeing it.
This is kind of an anti-feature: asking to be able to turn a feature off. Since this drop-down doesn't exist in Chrome AFAIK, I've never encountered it elsewhere.
