Using the immersive mode on an enchanting table only allows one enchantment to be selected (all 3 are the same enchantment), a fix I can think of would be (since scrolling through enchantments flips pages on the book in the overhaul), maybe right-clicking the book would allow you to scroll through them (a simple hand motion in VR).

Another fix I can think of would be have all of the options in a circle around the enchanting table and you can just look through them yourself.

There's also a config that allows you to add multiple enchantments, so that's also something to consider.

As for the enchantment description fix, maybe it could be like one of those scrolling ads, it slowly scrolls through the description if it's too long, allowing people to read them and make an informed choice without having to look it up on the internet, a real immersion breaker, especially in VR.

Can you link me to the first mod you mentioned, can't seem to track it down. No guarantees I'll implement it, as there's a lot of things I need to add to ImmersiveMC outside of mod compatibility still.

As for the descriptions, that's a really good idea! Will very likely add that sooner or later
