What is Stackpack?

I originally made Stackpack back in 2013, as a way of easily compressing vanilla blocks and items together.

This new Stackpack follows the same principal by acting as a hand-held storage drawer.

How to use

Once you have a packer, it will start out in "Configure" mode.

Hold an item or block in your off-hand, then place your packer in your main hand, then right click.

This will bind the packer to that specific item or block.

Then, use Shift-Right-Click to switch between modes.

For the "Pack" and "Unpack" mode, simply right click while holding the packer, and they'll do their thing.
