StayLapis

A simple utility mod that keeps lapis lazuli inside the enchanting table instead of returning it to your inventory when the menu is closed. Reopen the same table later, and your stored lapis will still be right where you left it.

Install on the server. Client installation is optional (vanilla clients can join and use it seamlessly).
Singleplayer note: Works perfectly in singleplayer. Just install it normally in your mods folder.

What it does:

• Prevents lapis from popping back into your inventory when you close the enchanting interface.
• Safely stores the remaining lapis inside that specific enchanting table.
• Instantly restores the lapis into the slot when you or another player open the same table again.
• Ties the stored lapis to the exact block position and dimension of the table.
• Automatically discards the stored lapis if the enchanting table block is broken or missing.
