Now that I use borderless and gapless windows by default, the window
management feature of kitty has become even more useful to me. This
change makes it easy to determine the active kitty window.
Despite having used tmux exclusively before, I have grown accustomed to
the benefits of using kitty as the window manager. tmux may still be
useful, for example, over ssh, but kitty is arguably the way to go for
local user sessions.
