I use the pocket ziplines plugin where you can change the name of that custom item.
Problem is that if I put these things in kits the name changes to the origin item that was used for that zipline, a tesla coil.
So, instead of "Zipline", which I chose as the custom name "Tesla Coil" is written.
This only happens with Rust Kits, not if I spawn these ziplines of have them in crates.

So, I would ask you to add support for custom names of custom items.
Guess there are many other plugins which have such custom items and names that would benefit from this.
Thank you.

Someday Kits will support custom names. But today is not that day. People have been asking for this for a while. 

:D This doesn't sound very hopeful.
