Hide Slack Sidebar Icons

#! /usr/bin/env bash
##############
##
## A script to inject a custom style into Slack that hides the new sidebar icons.
## This script has very little error catching or extra debug output
##
## Run at your own risk.
## Anything done here can be "uninstalled" by reinstalling Slack
##
## To run Slack in debug mode, run the following:
## export SLACK_DEVELOPER_MENU=true; open -a Slack
## With that, Slack will have a new Developer item under the View menu

# location of the preload file

# this script will add an extra style element to the head tag

THANK YOU, and to all of the devs who hacked this so I didn't have to. I really tried to give the new UI a chance, but the avatars make the sidebar too busy; it's an accessibility issue for some of us more neuroatypical types. At least the MacOS users in my co. can deal with this, and there's enough info in the script to tweak Linux AFAICT; Now to cobble together a technique for Windows and we're golden. KUDOS!!

@c133 I found this gist through another one: https://gist.github.com/joshua-turner/9310780782f6526fc8717d6798a4d4b9

The way shown there should work on Windows, but it won't persist. If you can find out how to edit preload.bundle.js for Windows Slack, you could adjust the script above.
