Have you ever tried to pick block from your creative inventory tabs and it didn't work?
with this mod you can!

Click middle click on any item display in guis!

This mod works by utilizing the DrawItem display method, which is commonly used in most (if not all) Minecraft containers. While Minecraft already includes a builtin pick block function for container interfaces, my mod expands on this functionality, allowing you to use it on any item rendered via the DrawItem method.
The mod is client side only, so it can be used in multiplayer. However, since only creative mode grants players the server side permission to pull items freely, the mod’s functionality is limited to creative inventories. In other interfaces, the server will override the mod’s behavior.
