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.
Since fish will warn when there are background processes before exiting,
and since when we type "exit" we really do want to close both the shell
and its corresponding terminal window, this change makes sense.
It turns out that neofetch works exceptionally well with this terminal
size, so I'm making it the default in kitty.
Now I can use neofetch without having to worry about resizing the
terminal window for the desired effect.
Since kitty would automatically assume a fullscreen or half screen size
as the default, it's much easier to simply specify the size all floating
windows should start out as.
Since kitty allows specifying the size in cells instead of pixels, it
is easy to achieve the same "actual" terminal size regardless of which
DPI is being used.
