When manually nesting lionesses, it's a little difficult for me to tell which are 3rd trimester and which are 2nd trimester without clicking on their profiles:



The top lioness is on her 3rd trimester, and needs to be nested today. The bottom lioness is on her 2nd trimester, and needs to be nested by tomorrow. It's a little difficult to tell them apart, which can lead to confusion.


I think that a saturation change would make it a bit easier to tell who's who, maybe an icon a bit more like this?:

Here's a mockup of the icons next to each other:


With a tweaked icon, it would be easier to tell which lioness needs to be nested immediately, and who can wait one more rollover.

EDIT: Adding to this, it is true that the nesting page lists which lionesses are pregnant for what amount of time. However, I mass-breed NCLs. My nesting page normally looks something like this:

In order to tell which trimester each lioness is on, I'll add a 1 to their name if I see that the icon displays that the lioness is on her 3rd trimester.

However, I have a hard time distinguishing between the 3rd trimester and 2nd trimester icons, making the process a bit awkward for me. Instead of checking only trimester 3 lionesses to rename them, I check both tri 3 and tri 2 lionesses to see which is which, making the process longer.

If the icon were changed, one would more easily be able to quickly rename only the lionesses that are on their 3rd trimester, and nest them more efficiently.
