Do whatever you want with this script, it's just a small script to add a button to hide/show the channel/user list on Discord to free up screen space. The button looks like a cat. It appears on the left guilds bar. A line can be altered to make it appear at the very top-right on the top toolbar of a given channel. Could break in future Discord versions, I may or may not update it then.
As Discord may contain adult content this script is marked accordingly.
