Dark themes, inline posts/comments, endless scrolling, subreddit filters, and other improvements for reddit.com
The script removes many UI elements by-default (e.g. Chat, Ads).
One of the default options is to hide the list of subs at the top.
This functionality is controlled by the NO SUBLIST option under the TWEAKS submenu. Unchecking this option will make the subs list appear.
I noticed in your screenshots that in the options menu above THEMES, it has a list of subs you're subscribed to. I don't have that. How can I see my subreddits?
