Limiting the tab asterisk in Slack

Question

I use Slack in my browser. Whenever anyone in any of the channels I have types a message (to me or in general), the asterisk is added.

Is there a way to limit the asterisk appearing for messages only in the channel I'm in/channels I want so that I don't have to check as often?

Answer 1

You can mute a channel. Then you will no longer receive any notifications for that channel incl. the asterix for new messages.

To mute a channel open it, click on the cog and then choose "Mute XXX".

Answer 2

I made a tampermonkey script for this: https://gist.github.com/rchernobelskiy/d8c71e6e1ebcdd22cf897ad28da875a3

Re-pasting here if easier:

// ==UserScript==
// @name         Slack tab title asterisk remover
// @namespace    http://roman.chernobelskiy/
// @version      0.1
// @description  Permanently keeps the asterisk out of slack's tab title.
// @author       Roman Chernobelskiy
// @match        https://app.slack.com/*
// @grant        none
// ==/UserScript==

(function() {
    'use strict';
    new MutationObserver(function() {
        if(document.title.indexOf('*') != -1) document.title = document.title.replace('*', '');
    }).observe(document.querySelector('title'), {
        subtree: true,
        characterData: true,
        childList: true
    });
})();
