Cool, that you liked my idea.
It was part of my job (several years ago) to improve UIs / Users experience.
So, I've thought of on another thing.
Because, sometimes, it's hard in the game what to do next, and this leads to an absolute necessitty of a walkthrough (that shows there is a pb).
So this interface, will show the current status for each girl, and provides hints for the next stages.
It's an interface to summerize in a single location all the informations for one girl.
So, you can display the Relation level (the stars) that are not displayed at all now,
display Heart/Lust/Dominance levels, and if they are maxed or not for the current relation level (and for the current update).
Finnally, each time you meet the girl in a location, it writes in this interface the location and the hour.
For this interface, I have thought of an "organizer" interface displayed when you click on the date (top left), but maybe you can do it with the smartphone.
So, here it is :
