I'm not quite sure if anyone has made a post/topic on this subject yet so i apologize in advance if someone already has.
Custom Skins, something i have wanted Craig to implement since 2013. If there was a way to create your own skins to use in game. Maybe create a website were you can create your skins pixel by pixel, kind of like the popular Minecraft skin creator website. I feel that adding custom skins would make each player more unique and give players more of a choice compared to the standard skins. People would really enjoy this feature if it was somehow implemented. It's not a 'must add' but it would be cool.
