Thanks for your site, and to the GP who made Don't Mess With Paste!

Feel free to add this if you want, I have it in my firefox called "UnfuckSlack" which puts the old slack UI back:

javascript:(function() { localStorage.setItem("localConfig_v2", localStorage.getItem("localConfig_v2").replace(/\"is_unified_user_client_enabled\":true/g, '\"is_unified_user_client_enabled\":false')); location.reload(); })();
