I think it's specially useful for small laptop screens, this is how it looks trying to have 2 windows open at the same time on Windows 10 (1280 x 800): https://i.imgur.com/vCWuoYA.png https://i.imgur.com/vCWuoYA.png - Code is too small to be readable by some (this extension allows zooming with mouse-wheel and pinch-to-zoom) - Stacking console under makes it so you can only see 15 lines of code at time (unlike the 30 you get without stacking) - A lot of horizontal space is wasted on scroll-bars, the edge of chrome and a few other elements
