I see that there is no categories for Adventure mode. Why no adding some?

The most obvious to me is Demon% : kill a demon as fast as possible in Adventure mode.

There could be also a Necro% category : read a life and death text and become a necromancer as fast as possible. Or a Slab% category : read a vault slab as fast as possible.

Perhaps a Demonic Slave% category : Have a demon follower as fast as possible, whether it is undead or alive.
