And dyes; I've always been a fan of dyes...
Dyes, I think, would be great because as the game currently goes, my favorite armor, malachite, isn't really viable when something more substantial than, say, a stiff breeze spawns at my gates. But I love how it makes my gnomes look like linebackers. Being able to add color to armor would be awesome. Even better, adding color to clothes so my non-soldiers can benefit!
This! THIS! This!
It is hardly game changing, but so many times I have looked at my gnomes and wondered why a particular line of work was being neglected. Sure you can go to the population screen and look up individuals, then go to their location, but it would be nice to see at a glance "all 4 blue clad gnomes are in bed, so the forges are done for the night." Even being able to easily spot the odd professions working on tasks far down on their list (like the cook hauling dirt) could throw out a sign that something in the production line isn't right.
P.S., it would also make it a lot easier for next of kin to identify the bodies. It is a thankless task, but think of the poor gnomoms!
Just my 2 cents on the whole "Life Sim" bit. I personally would be delighted even if there were just a handful of personality types and a favorite food/drink variable that just adjusted the gnomes personal stats. For instance, Kevin likes cheese omlets and orange wine and will choose that over any other food/drink. Kevin gets more food/drink points from his favorite foods or gets less points from things not his favorite (or even a dislike variable).If
gnome reproduction is ever added, a simple 4-8 personality types where say 4's are only attracted to 1's (and visa-versa) would provide an added "depth" there without becoming a complicated, overbearing system.
As I am NOT a coder, I just took a guess at what should simply be a stat modifier for an individual gnome, which hopefully translates into "easy to code!"
