A regular rightclick will teleport you forward 30 blocks, if the targeted location is an Air block. The "Teleport Reelback" keybind will decrease this distance by 1 block, while the "Teleport Extend" keybind will increase it by 1 block. You'll also get a handy particle effect at the target location, so you can see where you're going to land. A shift-rightclick will set you into Spectator mode for 5 seconds.
This was made in MCreator, however I tried very hard to make it a high quality mod.
