The project view that shows thumbnails of all artboards should scale lower than 10% (2,3,4 % even) if needed - otherwise at the moment when the project file is wider it gets cut off by the browser - you can still navigate it using mouse and holding space to drag, but most devs I know find it awkward if they want to jump from screen to screen. If they use 1366px screen than often projects don't fit at 10%.

"ok.png" shows me fixing it by moving artboards into a smaller column, "bad.png" shows how it looks on screens with lower resolution.
