I've put together a mod extension called
ComplexBreeding.AutoSell help you progress faster with less time spent checking stats when playing ComplexBreeding.
The complex breeding mod is amazing but I've found it adds a lot of extra work looking through all of the generated offspring. I often wanted strict control over what stats I'm looking for and an automated system to get rid of the rest. ComplexBreeding.AutoSell still requires some management but less overall.
The mod lets you configure what offspring you want to be automatically sold to a very specific degree. For each species you can pick what essences, traits and tits/womb size are required to keep the offspring. Over time you increase the requirements to build up better units.
Creating a UI to manage it in the game wasn't feasible so I've split it into two parts. There's a mod that applies the configured rules and a web page (local html file) that is used to configure the rules. The UI is pretty rough. There are more detailed instructions on how to use it at the bottom of the configuration page. This mod will replace and disable the autosell functionality already in ComplexBreeding.
