wood be nice to allow us to stop the spawn of something out right like i do want spiters as im not a fan of thim so a setting that makes thim not spawn

I'm not a actively working on this mod (thought I'd closed it tbh).
Your suggestion is very valid.
In case I return to this mod: mod option to disable the creation of specific spawner types, e.g. spitter spawner.
As just disabling specific unit types would leave the spawner absorbing pollution and not creating anything. Or would remove the unit(s) producible during a specific evolution range.
