Eelytra Slot adds an extra slot for wearing an Elytra, so you can keep your Elytra equipped without replacing your chestplate.
Basically, it gives the Elytra its own place to go.
The mod is standalone and does not require Trinkets, Accessories, or any other slot API.
It also supports Mending repair while the Elytra is in that slot. When you collect XP, a damaged Elytra with Mending can repair from that XP.
Eelytra Slot does not change how Elytra fly and does not add new items. It only adds a separate Elytra slot and makes sure repair works properly there.
More loader/client support may be added later.
