I pushed a new version that contains a new "Toolbox" item.
- It can be obtained via the command "give toolbox"
- It is intended to provide tools for structure template creation in future
- For now however it already offers you a way to get blocks
- Shapeless blocks can be obtained in any wished shape
- It works in multiplayer (In my quick test at least)
- It uses tree view component @rzats made in GSOC
