I'd like the pick block button to select the targeted block type for placement if the /dank/null contains the targeted block. This would make base building a lot more convenient, because you wouldn't have to shift scroll, just single button press to switch building blocks.

you can also open the GUI and Alt+click the block...but I do like this idea..I'll see what I can do..thanks for the suggestion

It should as I use a vanilla method to check for the key press which takes all OSes into account

At any rate I posted a gif of this functionality (pick block) in action on my Twitter (@TheRealp455w0rd)
