I feel like the icon of promoted specialists should look different to normal specialists. Like, because they're different and you spent 2 hires to get them, they're more powerful and many of them have global effects. Also they have a star on top of them to show you can promote them, so why should they looks just like any other specialist once you do promote them? Its just nice to be able to distinguish these from the normal ones instantly.

It won't really require a lot of programming or anything either, like I was thinking maybe you can just invert the colours so that there is a white icon on a black background or something like that. It might also be applied to the queen... idk

I know its a small point, but its often the accumulation of these small points that distinguish a good game from a brilliant game, which I feel subterfuge has the potential to be. (I mean, its still a great game and I'm enjoying it!)

Agree with this, maybe a nice coloured outline or something would be very handy for at-a-glance identifying of promoted specialists

Gold might be a nice colour then again any colour other than white and black may clash with a players colour sometimes.
