Thank you for the suggestion! The pregnant girls are already listed on the Check List page at the top as "Attending the next festival", but I will consider showing an "Is Pregnant" text right next to their Jump button. Thank you!
Yeah I saw them there, the issue is that you have to read that list and then cross compare with the list of characters, so when I've done 75% of them say and am thinking "OK, who is left," it's not a convenient way to figure that out. Actually another bit of information that would be good on this screen is what percentage cost reduction each character is at.
