Hold E for Quick Inventory Access. Release E to Close.

The quick inventory is another method for viewing the inventory. It can be seen by holding E, and will close upon releasing E.

This feature is compatible with the current, toggleable inventory. Ideally, this will allow players to access their inventory whilst moving and/or crouching, fixing interruptions in combat and sneaking.

An inventory quick-access feature would work as an intuitive improvement on inventory-to-hotbar management. The current inventory GUI may be used, thus requiring very little to implement.
