Mojang prioritizes issues that have the most votes in their bug tracker, so if we want specific things fixed, we should work together. How? Find an issue that bothers you on https://bugs.mojang.com/browse/MC Post the issue in this thread Let the rest of ShadeCrest upvote the same issue ... profit? Side note, if you find a "new" Minecraft bug, make sure you check the issue tracker thoroughly. In most cases, it has already been reported, and you should just upvote that report.
