Cardboard: a scrollable tiling window manager
In essence, this is similar how I setup and use Spaces on macOS. Have a number of spaces that are horizontally laid out with a three finger left/right swipe between them.<p>For each Space, you can make the apps full-screen or split screen to have variable width windows. Of course you don't need to make them full screen but it does keep it simple similar to Cardboard.<p>The added functionality with this approach is that you can use the Space as a casual grouping of windows in a related project.
