i know this one might require some rewriting and/or checks, but having her pay attention to if she has arms/legs or not when things happen.. or they're added. also when doing dialogue like when anon asks if she can do the dishes, she could respond "when i have arms and legs, yes." or something like. she could also comment on them when they're first attached.
the stream audience could even react to the presence of new arms/legs/colors too. (for immersion)
also.. a tail to go with the ears. not a butt plug, but a tail attachment. maybe even furry cat paw arms and legs too. related, if doing said tail and alternate limbs, bunny tail and ears too.
alternate bust sizes for her. i know it's already mentioned but it could be a part swap or simply a setting on the computer interface for her.
more of an edit than anything, but after you name her, change her name from "bot" to her new name when in dialogue with her.
not sure if it's just the version i'm playing, but an option to change position after having started sex with her. or to stop at any time, before running out of cum.
alternate positions like hot dogging or taco would just be a slight alteration to the current animations. 1st person of doggy would be nice. being able to lift her leg/legs during missionary, or wrap them around you. tit fucking, would require arms.. could cum in her mouth or on her face.
ability to have her vocal during sex or not. she could moan, beg or make other sex sounds. this could be a simple option when opting to have sex with her. radial button for bot's vocals on/off or something like
maybe even some alternate positions for her instead of just being covered by the blanket all the time. she'd of course go back to that blanket covered state when someone knocks on the door. this would require limbs of course.
oh.. and to keep all the food and drugs at the top of the items list and all the robot parts at the bottom, mine got all mixed up for some reason.
