From bef83ecfe66bb83a8420239f8c068cf60d2c3e0c Mon Sep 17 00:00:00 2001
From: Bakkeby <bakkeby@gmail.com>
Date: Mon, 10 Jan 2022 14:07:02 +0100
Subject: [PATCH 2/2] Adding awesomebar barmodules patch.

Note that this patch does not come with bound ClkWinTitle button click
actions for extra behaviour when clicking on the window name in the bar.

The original bartabgroups patch included hardcoded focus on click which
has been replaced with a generic click for barmodules.

The intention here is that this is combined with the wintitleactions
patch that allow clients to be focused, zoomed and hidden - functionality
that has been separated from the original awesomebar patch.

In other words, all this patch does is showing all window titles in the
title bar with an even split between them.
