+# Handy for opening images and videos "inside" a terminal.

+# This effect is similar to dwm's window swallowing patch: https://www.youtube.com/watch?v=92uo5OBOKfY

+# To be super minimal, configure i3 to use a 0px font size to hide the tab title bars. With the
+# unfortunate caveat that this will cause i3 error messages to become unreadable.
