Tabbed DropDown Alacritty for X11

# This script can be used as a launcher for alacritty-inside-tabbed
# It monitors window manager events and when detects that tabbed has
# lost focus, script will minimize tabbed.
# If alacritty-in-tabbed is not running, it will launch it, if it is
# running but isn't focused, script will give it focus, if it is running
# and is focused, script will minimize it.
#
# The script should work in any POSIX compatible shell (at least according
# to ShellCheck), but was only tested on ZSH. In case something doesn't
# work as expected, please submit a PR or report the issue in a comment.

# TODO: get rid of mentions of tabbed to make script universal.
# TODO: investigate why are there always two copies of the script running

43'rd line was causing me problems so i modified it to work
*_NET_WM_STATE_FOCUSED* )
to
*_NET_WM_STATE_[^:HIDDEN:]* )
nice gist by the way

Thaks for the feedback, I'll test that and if it works for me as well, will update the gist.
