As a lifelong Mac user, I'm mildly tempted to do something like this in SteamOS, but with limited real estate: two panels feels like potentially wasting pixels, and the bottom edge is probably easier to reach on a touchscreen gaming handheld. I'll do some tweaking, but the ultimate UX has to feel right on this device, not just familiar to what I use elsewhere. Plus, I mostly use Desktop Mode for Chrome, which doesn't really use the menu bar.

But I appreciate the share!
