[+] You can use portals now! With the new portal editor in the hotbar, you can easily create some portals with different animations and particles. You can change the radius, the height of the hologram-tag or animation circle. You can change the animation type (circle or other stuff) or add a permission to the portal.
[~] Command-Changes: Sepperate the command /warps and /warp. With /Warps, you can open the gui like the old way you did. With /warp, you can teleport yourself instantly (if there is a delay, then you start the delay) to the warp.
