Appreciate the kind words, now to answer those questions.:
"what is the function of the four dot square button in management screen?": The vanilla factions have townscreens and that's the button to switch from clasic town view to said town screens but since mods don't and can't have them currently then it serves no purpose.
"Do you intend to post your other faction mods here too?":
Don't really see a reason for it right now but that might change in the future.
"Are the bots using the faction familiar with using the evolution chamber and so on (do they pay the premium, hindering them)? Or are their armies generated automatically?": Colony's AI seems to work just like other AI but they don't seem to use the Library oof Evolutioni s what I've noticed, that'd be more of a question for the dev ThingsOnItsOwn sorry. I do know their armies are not generated automatically unless they have mastery which gives them certain unit every X days.
