What are your favorite lessor known, or "hidden" features in Alien Blue?

Someone suggested we have a list of things that most people may not know Alien Blue included, and I think it's a good idea. Post your favorite features, and I'll add this thread to the sidebar so everyone can check it out!

Mine are:

• Tapping a post or comment with two fingers upvotes it
• Going to reddits, and clicking the arrow next to the subreddit name will bring up that subreddit's sidebar
• To search within a subreddit, go into that subreddit via the reddits page and tap the search icon (probably well known, but I've seen a lot of questions about it)
• Only really useful for mods, but you can view your modqueue by adding the casual subreddit r/mod/about/modqueue

Let me know what I've forgotten, or just don't know!
