• Ctrl + middle click to pick up tuned note blocks.
• Right click will always open tuning GUI. No need for a book any more.
• You can toggle that off with /blocktuner command. To turn it back on, use the same command.

Now server will require you to have a compatible version of BlockTuner, otherwise you are treated as without the mod.
