This mod allows you to add/remove/edit spawns live in game, with an easy-to-use widget that's accessed from the buff radial menu (Hold R on PC and must be logged in as admin)
Quick run down, min desired amount is the absolute minimum amount it wont stop spawning until, the desired amount is what it will try to get to depending on spawn caps etc.
Entry weight (0-1 including decimal value) is the likely hood of that category getting picking to spawn, so say you have dodo at 1 entry weight and pego at 0,5, the dodo category has a greater chance at being selected over the pego.
The Spawn percentage chance (0-1 inlcuding decimal value). So say you have 2 dodos in there, first one at 1, second at 0.5, the first dodo will always spawn if that category is selected, second dodo has a 50% chance to spawn along side the first dodo if the category is selected.
