My fixed-up, still-barely-maintained EnhancedDiscord fork. Original README follows below.
A lightweight client mod designed to enhance your Discord experience without slowing down your PC.
Using EnhancedDiscord, or any other client mod, is against Discord's Terms of Service. Use it at your own risk. It's very unlikely any action will be taken against you, but we take no responsibility if anything happens.
Go to https://enhanceddiscord.com and hit the 'Download' button, or if you're lazy, click here.
For more info, including installing on Linux or MacOS, see the installation wiki page.
By default, the official EnhancedDiscord theme is loaded along with a plugin that allows you to change settings of it in User Settings > EnhancedDiscord > Settings. For more info on how to change/edit your theme, see the FAQ.
A list of included plugins and their purpose is included on the plugins wiki page. It also includes some sources for finding new ED plugins.
For info about how to create your own plugins, check out the custom plugins wiki page.
First, check out the FAQ to see if your issue is listed there. If not, ask in #support in the support server (link below.)
