Open workbench, enderchest and enchantment table from your hand.
No need for commands! Simply shift + left-click and the container will open.
This is especially useful for enderchests as you don't need silk-touch to pick it back up.

Permissions are

• portablocks.use.workbench
• portablocks.use.enchantment_table
• portablocks.use.ender_chest
• portablocks.use.shulker_box
