Literally begging you to add gender expression/appearance and roommate gender to custom gender. A transmasc character shouldn't be forced to room with a girl and have NPCs who are only into women be attracted to them because you decided "they/them + vagina = Girl Lite". It's really not a custom gender, you just reassign them to an existing one
Same thing with non-binary presets and NPCs just being treated as their AGAB 95% of the time.
