Better Pick Block

When I'm playing Minecraft I often use the pick block function to select blocks. Sometimes it happens that my hotbar doesn't have a free slot and my pickaxe, or some other tool I needed is moved to my inventory and replaced by the picked Block. This is infuriating and the reason I created this mod. 

This mod makes it so that tools and other important items are not replaced by pick block. You can also specify alternative blocks that will be picked if you don't have the right block in your inventory.

For example: I want to cover up a hole in the ground so I pick block a grass block. I don't have any grass blocks in my inventory so a dirt block will be used instead.

You can configure which items shouldn't be replaced and item alternatives in .minecraft/config/bpbconfig.hcl
