I have recently been working on a mod that added more nether-related items to mcpe. This mod will not teleport you too the nether but if anyone is making a nether custom map to use with a nether portal mod or if they want a few new features ntheir game this is a great mod. The mod code is 24946, this will always be the latest stable release,remember when you start up block launcher reinstall the code to check for updates. Downloads for specific versions are available below. I would love to suggestions but I won't add netherwart, or portals, I tried them and they were beyod my abilities.
