If you haven't tried, after you use Cmd-Ctrl-F to make Chrome fullscreen you can use Cmd-Shift-F to toggle the UI elements (tabs, search bar & bookmark bar). Although it doesn't follow your mouse hover which is somehow annoying.
fullscreen != fullwindow
Cmd+s in Arc just hides all the UI of the browser but does not change the size of the window frame. This is more akin to Chrome's add shortcut to desktop feature, except that it is easy to toggle on/off with a keyboard shortcut. So if you have a web app you want to just focus on, you can just do so.

Interesting. I'm not happy with how Chrome handles fullscreen either.
Actually, this is my favorite part about Arc. Most of the time when using Arc I'm working in fullscreen mode with 100% of the UI hidden. There is literally zero on my screen except the page itself. If I mouseover to the left (or hit cmd-S) I can see the sidebar/addressbar etc.
It's absolutely wonderful and really puts the focus on the content. I find it much better than how Chrome handles fullscreen.
