IE9/IE10 Browser Concept for WP7/WP8

I dislike how the back button in IE behaves differently after switching between apps. I really dislike how adding forward and find functionality requires a hack.

The customizable button in in IE10 is confusing. How do users know this functionality exists unless they poke around in the settings? How do refresh if you set the button to forward?

Anyway, I decided to try to come up with a UI for IE that I can live with. Keep in mind that these were made in Paint in about 30 minutes and I'm no UI or graphic designer:

45wzu_medium

54nb1_medium

Clk5m_medium

Ovleq_medium

So, what do you think? Tabs are still on a separate screen, but this is supposed to be recognizable as IE.
