Love this mod. Couple suggestions:

1) It would be great to have a checkbox to show ghosts of all items you have unlocked. That way you can pick/place a ghost even if you don't have it in your inventory.
2) Wound be nice to have a way sort items by the exact layout of the crafting menu (with blank space) and tabs or arrows to move sections.
3) Or a way to manually sort.

Unfortunatly these things are kinda outside the scope of this mod.

Especially the sorting, I use an API function that gives me that exact order for the items because its miles faster than manually looping through the inventory, so I have no control over the order of things displayed, atleast not without like a large change to how the mod works.

And showing every building you have unlocked is kinda counter to the point of the mod, especially in large modpacks with hundred+ new buildings, it would just flood the menu with ghost items XD
