From the notes, the diary/biography layer seems a useful way to make residents memorable beyond their jobs. One thing I would check in the new overview: can a player distinguish “nothing known” from “known healthy” without relying on green alone? A small symbol or label alongside the colour could make that distinction easier to read.
For the couples and quarrels, does the diary explain what caused the change, or only record that it happened? Seeing the cause would help me understand the person rather than treat the relationship as another status meter. I have not played this version; these are questions from the update description.
