Adds controller and touch screen support. I use this to play MC remotely on my phone.

Good to know, thanks ion. I'll consider adding it!

I won't add this because I believe this is a client-side mod so players can add it one case-by-case basis. I want to avoid potential conflicts if possible, unless it can be confirmed that there's NO cause for concern.

Also pretty cool that you play onthe phone!

It has a server side that allows disabling/enabling some features. They are disabled by default when connecting to a server if the server has no plugin to stop "cheating"
