Describe the feature you have in mind.

So to keep the mod in line with the create mod, the jetpacks shouldn't have durability, similar to how the backtanks are with the create mod. Because as the mod stands currently, the jetpacks have durability, but without F3+H, you can't see it. I propose that either, the jetpack supports the Mending enchantment, or that the mod takes the same approach that base Create does, and simply do away with the durability.

I took the liberty to test if the mending enchantment would work as intended in my singleplayer world by adding the enchantment via command: /give @p create_jetpack:jetpack{Enchantments:[{id:"mending",lvl:1}]}

I'm currently using the 1.20.1 Fabric version of the mod on a large modded server.

Does this solve a particular problem?

Yes, it stops the jetpack from breaking when the player isn't expecting it.

This definitely is a bug, they are not intended to have durability

Ok looks like this is a fabric-only problem, will release a hotfix soon where durability is removed for jetpacks

Perfect thanks
