The features we are working on are needed on the site. Some people won't think they have the same priority than others, but you can't please everyone.
We updated the entire look and flow of the site with Game Jolt Next. This was because the site was getting very old and very hard to maintain. We wanted to improve a lot of things, but in its previous state we couldn't.
We added the ability to use the site and functionality as a standalone app due to how efficient it would be for people to download games.
We updated the forums to keep it consistent with the rest of the site, as well as improving the way discussion works.
We are going to release marketplace to finally let people sell games.
Not sure which of these features were useless, but in my opinion the order these were released was fine. Things will break because we're a small team and nothing is perfect.
Now the list of features to come have been chosen for a reason. They are ordered by significance. Devlogs, for instance, is to combat the big problem of unreleased games dominating the site. A lot of people just want to play games, but the majority of the games they find are unplayable. With devlogs we can finally separate released and unreleased games, as well as improve the way you as a developer can share content with other users.
The reason why we haven't done group features yet is because of the biggest factor - we need marketplace to be done. This is an entirely new feature that needs to be thought about a lot and isn't an improvement like the other features.
As with the new rating system discussion, that's all it is - a discussion. I just wanted to know people's thoughts. Heck, I don't even know when or if that'll happen.
