As tumblr user ommanyte said, "how dull for you to live your life without any hills to die on, you, on your vast flat barren plains of compromise, acceptance, and accommodation, while I reign supreme over the lush, rolling highlands of stupid shit I have irrationally chosen to stake my entire identity on"
Now this is poetry. I chose keybindings, but I respect the domain of window manager aesthetics.
He didn't say that he had no hills to die on, just that rounded window corners isn't one of them.
