I think adding the option to adjust the refund values/percentage of weapons sold back would be nice.
Example: I would like to adjust the 25% amount gained from selling weapons to 50% (like in KF2)

Related to Re-spawning ammo. Would it be possible for armor batteries to spawn randomly along side the ammo boxes? (Along side a config option for it, for custom items)

Thanks if you took the time to look at the suggestion.
