SmartCord
SmartCord is a modification for the Discord desktop app that allows you to load themes and plugins easily, quickly, and safely.
It comes with a theme loader, beautiful customizable theme with image background, and many plugins.
It also, by default, disables Discord's telemetry. This prevents Discord from collecting and potentially distributing data about what you're doing on Discord.
In addition, there is a built-in option to enable silent typing, so that you never appear as typing in any server.

Themes
SmartCord comes with a CSS loader, which can be used to load almost any theme. Here's an example of the default theme:
