Forum Themes and Other Customization

Just putting it out there that I’m not familiar with Discourse nor what you can and cannot add, so stop me here if I’m dreaming.

I’d like to know what the chances of adding some customization to the forum is, such as backgrounds, light and dark themes, more compact or expanded views, etc. This all would be pretty neat, and many forums do have their own version of this.

What I found out from Wikipedia, is that Discourse does not support custom forum themes. Other customization could be available via a plugin though. Views and little stuff like this is probably determined by forum admins, and might not be available for personal customization, but as I said, this could change with a plugin.
