Could  plugin - the quantities of loot have to be adjusted one click at a time. For instance if you wanted to add 50 HV ammo to the loot you would have to click the ammo 50 times. Otherwise a clean / simple plugin that isn't as powerful as Alpha loot but much more user friendly. 

Nice plugin but with the UI you can not set proper amount you should be able to edit amount instantly instead of clicking 1 at a time at this point the UI is pretty useless. You also can not set the min amount and max amount to the same number with the UI you can only do this by unloading the plugin editing the data file then reloading it. You can't set the rarity of the item or the chance of it spawning in the crates. If the plugin is to be adjusted I'd give it a 5/5 but as it is the free betterloot plugin is good option but keep in mind this allows custom items in crates.
