REQUEST: Increase the maximum Sim body weight.
I know this might be seen as an undesirable update, but I think it would be a lot more realistic if the fattest that Sims could get in the game didn't just amount to them gaining a slight underline of their belly and losing their abdominal toning/muscles. I just think that with the quality of the character models, it wouldn't be beyond the realm of possibility to maybe add some 3D rolls or a more prominent belly. I mean, they do it for pregnant Sims, but not for fat Sims. And I know they recently added stretch marks, but it's just the SHAPE of the Sims' bodies doesn't necessarily convey it.
Just something I'd like to see. Oh and PLEASE add the "secret weight/muscle levels" to the directly accessible slider. You almost certainly already know that the muscle/weight sliders can only be adjusted to a maximum of one stage lower than the in-live-mode maximum. If you want them to reach true max-muscle/max-weight is by making them continue to workout/eat AFTER reaching the "max" muscle/weight slider.
