Whenever I'm going through my den, sometimes I want to check on which wolves are expecting pups and when they'll be ready for the nest before the timer is actually done. With multiple expecting and multiple resting, this ends up being difficult if I've forgotten who is expecting and I end up clicking on a bunch of resting wolves instead of anyone expecting. This is annoying already when only breeding a couple pairs of wolves, but I imagine it's even more frustrating for larger dens with even more pairs that are expecting and resting at the same time.
It'd be nice if the icon for resting wolves was different from the same hourglass used for expecting/in labor wolves in order to solve this issue. The icon for expecting could be changed alternatively, but I prefer having a new/altered resting icon. Something as simple as a "Zzz" would be really helpful as a small QOL thing. :)
