I am not a dev, but i think i've seen some active comunity members answering similar questions already
1) "adjustable body parts (boobs, Thigts). this would require a lot of work from the dev. highly customaizable character has it drawbacks, as all body types and all clothes will need to be accounted for all postions, or models the bot may have (standing, sitting, sex positions, ect). implementation based on polls. support is growing for this suggestion."
So, in short, "who knows, if patreons vote for such stuff, it might be added"
2) if i rembember things correctly, story is concidered complete for around 60%
