It turns out that kitty has support to change all of its colors
independently from the current terminal with a simple command. This
was the only issue I had with making pywal and kitty work together,
so I'm glad I found it.
Additionally, kitty supports DPI changes immediately (at least with
xrdb). There is no need to detach a session and open a new terminal
since kitty will handle DPI changes automatically, compared to other
terminals like urxvt, which would require a new instance. Even then,
the border padding for urxvt is not adjusted to the new DPI; kitty
is simply the way to go if your monitor setup is non-trivial.
As a side note, the kitty documentation is very good. I highly
recommend reading it if you plan to use kitty (which you should).
Since the community package doesn't include the fish completions found
upstream, we install them here instead. There is already a bug report
about the fish completions, and when it eventually gets fixed, these
steps can be removed from the PKGBUILD.
