> If you look at the setup that's exactly what is happening. On a single screen there is browser with documentation (presumably), and there is four (!) IDE/editor/terminal windows.

Just to clarify: there are two i3 containers side by side (each using 50%). The left one’s active window is a browser, the right one’s active window is Emacs, in which I have two buffers side by side at the top, and compilation mode and magit status side by side at the bottom.
