It may be a good idea to have an 'Arc' like mode in Orion. The closest emulation is Orion's full screen mode with auto-hiding sidebar. These same features would be just as useful in the regular view (non full-screen), or Focus mode. Using other apps becomes easier in regular mode. At the moment a key combo or pointer click is required to open/close the sidebar. Auto-hide for the sidebar please. Fleshing out Focus mode to be more like 'Arc', would be great!
Arc Browser
I think Arc's well thought out balance between a clean minimalist look and usability is excellent. Arc shows just enough display information to open tabs, windows etc; then all of that gets out of the way when browsing. Brilliant! The floating chromeless window is truly attractive; it almost doesn't need a full-screen mode, its that efficient with display space.
P.S.
I'm mainly drawn to Orion because of its highly performant Webkit engine, and default blocking of ads/trackers. Arc's use of the Chromium engine results in slight stuttering with scrolling motion, and greater fan use on my old '15 Macbook Pro.
Would it be so shameless to copy Arc's UI and command bar?? :
