Separate slots for things like jet packs

We also came up with the notion that we would add another inventory hotbar. Non-weapon items (such as speed shoes and the Jetpack), would be placed on a separate hotbar than weapon items (condo tools, potato gun, etc). The Weapon hotbar would use the 1-8 keys to quickly switch between the different weapons.

This is planned with the release of condo tools.
