Now you can store all your netherite in a clock
From v1.1 only
I even installed AE for you. Guess what? It works!
WAILA even shows a cute watermark in the tooltip. Just don't put morphed stackable things into AE, ok? P.S. Idk who broke the textures.
Here. Akashic tome of Akashic tome.. ×5 with Akashic Tome in it.
All duplicate data is replaced with "AkashicDummy", so it doen't take twice the space.
Here, now you can see.

What are you holding? A bow?!
No, it is actually an ItemStackWrap, which is a tome, (quite successfully) pretending to be a bow.
Currently you can't put morphed tomes into tomes
Why would you need to anyway?
Crafting also works fine
Don't get scared, you have just triggered an attachment recipe while taking the books out, so now one of them will have the missing one inside. Just detach it with ctrl+shift+q.
Just like this.
Did you expect dry sponge to also be a tome? No, I don't have such technologies (yet)
Everything here is a tome

Mean. (Fixed)
From v1.1 you can use water buckets and potions comfortably.
Or the other way round )
All that can will just burn, netherite will be safe
Feel free to morph it into a piece of netherite and drop it into some lava.

If you leave 0 items in it, it just morphs back
You can perform some basic operations on stacks, pick items up into them, split them in half, merge. All while not deleting or duplicating anything.
Or unbrick it by adding the first item
In crafting table you can just shift-click items into it.
Works.

Works with redstone

Can use bundle-style hint
Actually the same as bundle except first slot
Items are ordered newest first

Works in offhand
Yes, I put 300 totems in it, but it will unmorph each time one is used.
