I like the idea of a teleport hat, because of the relation to the enderman. Ender Pearls should be used to craft it. A hat rack is a nice idea, too.

Hatrack
Block where you can place hats & helmets. Like Armor Stands but only for hats.
There is a mod with Hat Stands: https://www.curseforge.com/minecraft/mc-mods/hat-stands

Ender Hat
Effects: Linkable to a Hatrack to teleport. Maybe eat Ender Pearls when on head to teleport?

Hatracks are implemented in another issue #34

Ender Helmet implemented. Released in next update.
