+** Window management
+Window management is really important. I find the default window
+handling of Emacs incredibly annoying: sometimes consuming my windows,
+sometimes creating new ones. So, as Emacs is the ultimate editor, I
+want to configure and fine tune the window management of Emacs.
+
+As I am a man who requires only the highest of optimisations, I always
+am looking for ways to make my system faster. The buffer management
+commands are defined in the window library, so I bind them in general
+here as well via a wrapping use-package declaration.
