6. Dislike button. If there's one feature many people want but likely will never get, this is it. Although websites such as YouTube, Reddit and others allow their users to vote thumbs-down or down-vote an item, Facebook only lets users “like” things. But not everything is sunshine and rainbows, Facebook. Let us dislike too.
7. Favorite posts. A neat feature that Facebook could borrow from Twitter is the ability to favorite a post. “Favoriting” on Twitter allows users to essentially bookmark their favorite tweets and easily pull them up whenever they want to. Right now, there is no equivalent on Facebook, which makes it difficult to find something a friend posted a few months or years back.
8. “Want” button. There's a difference between liking something and wanting something, and a number of Facebook users want to make that distinction. Pressing a “Want” button could let users create wish lists of products they want and allow others to see those items. We know Facebook is testing the feature, but the company has yet to expand it to all users.
9. Facebook Wi-Fi. In November, we learned that Facebook was testing a product that would allow users at participating retailers to access the store's Wi-Fi network simply by checking in with their Facebook profiles. “Facebook Wi-Fi” seems like a solid idea that would make it quicker for users to access stores' Wi-Fi networks, but we haven't heard anything else about Facebook Wi-Fi since we first found out the company was testing it.
