Hm, that might be possible.. they use MIT license, so anyone can do whatever they want to the code. Though it would take a bit of testing to know what I need to keep and what can be discarded from the original mod.
That being said, I actually use the stdlib mod across all of my other mods, so I would either need to include each of those functions in each of those mods, or make another standalone mod as a dependency for all of mine. While technically doable, I remember the stdlib mod being shared across several of the mods I used, mainly the Picker suite, nanobots, bio industries, and natural evolution mods (though none of those have been updated either...)
I really want to hold out hope that Nexela comes back to update their mods, or that at least someone else can pick up where they left off (in terms of Picker, since I don't have much experience working with control.lua )
