Please consider a functionality to open ender pouch using button shortcut instead of having it in hotbar.

Probably the most straightforward way is how Backpacks mod does it:

• Shift + shortcut key - enables you to "equip" the backpack (open UI with a single slot)
• Shortcut key opens it

Thanks.

Not interested in this feature. Ender Storage is meant to be simple and compliment vanilla.
