Unless I'm blind, is there a way to determine when a player is waiting to be teleported in EssentialsX? Basically I'd like to play a particle effect while the player is warming up to teleport. This is currently how I'm (dumbly) doing it: https://github.com/MLG-Fortress/MountainDewritoes/blob/master/src/main/java/me/robomwm/MountainDewritoes/TeleportingEffects.java

Short of re-implementing teleportation commands, I'm not aware of any other way to do this while using EssentialsX' teleportation. Is it possible an API/event can be added for this?

Nothing currently but PRs are always nice <3

There is Essentials.getUser().getTeleport(), maybe you could use that to check if the teleport is still active at least? Unsure if it works as expected.

Not sure if you still need this, but as drtshock mentioned, PR's are always welcome.
