Haii , I think that it would be super cool if we could like have 'roles' (job) like hunters, gathers , fishers and stuff like that. So that a Nichling could have a role like the system with alpha, beta and omega. I'm not sure how handy this would be if at all but I think that it could work with the automatic perform job you guys where talking about.
I also have other (small) suggestions, the first is for a new location??(not sure if they are called locations) But a very volcanic location would be really cool or a completely under water one with just a few super small 'islands' and underwater ports. Stuff like sharks and other big predators could be added and there could be underwater wanderers.
My other suggestion is for underwater nests, so they look different and maybe leaches cant get on them if a nichling is resting there, I think that it would be really cool. Also more under water related food could be amazing, like maybe squids and stuff like that this could tie in with the underwater world c;
My last suggestion is for an intelligence skill(trait?), this skill could make your nichelings make better nests(maybe like the permanent nest) just like beavers in real life can make really good nests. And im not sure how realistic you guys want to keep the game but it would be also cool if the intelligent nichlings could make small barriers like they make nests but just like the thorns in the swamp location. It would be so cool if that would be possible, I'm sorry for my big message.
Also I dont know a lot about this game so maybe many things that I suggested are already in the game, thanks for reading this message if anyone really did haha.
