it would be great for the ability to love on one's footpaws, and as for the growth/macro bit, perhaps a grow/shrink gun, with whatever slight limits if needed

This is my list of things I feel people may want but are mostly just my personal desires, to be at a point where I feel like I have enough control over character creation to be fully satisfied, given how much is possible already.

1) Body/Facial Hair/Fur : A couple of presets (if possible given the already large variety of head shapes and such) for facial hair would be wonderful. I still haven't made a good looking beard in my messing around with embellishments. This could extend to other things, chest hair, armpits, etc. I am sure pubic hair would be nice, and personally, I would like to have a happy trail option or two.

2) Custom Textures : I may just be crazy but I believe i saw that custom textures are possible.  In my poor attempts to mess with game files and create some, I failed miserably. I am unsure what is required. A small tutorial would be nice to help those willing to test the water with custom textures. Again, I would personally like to have access to a happy trail type of texture. just a silly line down the front of the chest. I could not find a workaround combination to allow this currently, and it would be much simpler to have a texture instead of my dense line of fur embellishments attached to mis-colored chest textures.  A simple guide somewhere would work wonders, if it is even possible.

3) Part Deformation :  I won't have issue if this isn't possible, I understand the complexity this would open up. First off, I am thinking of scaling body parts differently. Have one arm longer or more buff than the other. That would be simple. But secondly and more so, partial/full deformation would be great.  Tear holes in parts like wings, add/remove fingers or limbs, things like that. Personally, I just want to deform an ear. Tatter it a fair bit, that's all. However I do not fault Fek or the game if it simply will never be possible. Extra polygons from deformation would surely screw things up on many levels.

TL;DR: People might like some preset body hairs, texture creation information, and part deformation. But I just really personally want happy trails outside of mass embellishments, and to shred an ear of mine That's all.

Incredible stuff so far though, Fek. I applaud you immensely.

Much like the way you can control breast perk, allow the player to control how much or how little a larger belly is affected by gravity/physics.

I would like this game to be support on the browser,like rack 1. I enjoy rack 1, and I do not want to download rack 2, do to a shared PC with minors on a separate user, so plz make rack 2 a browser game as well (does not have to be right away of course, you've got enough on your plate.

To have an option where you can choose if a character has only one or multiple parts like dicks or holes 

I have a fetish for balls. Sue me. Anyways, the ability to put a subject's pair of balls in your mouth, and gargle/slosh them around in your mouth. The way Fek makes (almost) everything jiggly, it'd be pretty hot. 

It would be nice if the characters you create has individual preferences

Pretty self explanatory, stimulate a subject by deeply "inspecting" their mouth with your hands, either before or after cuming inside 

A shop in which you can buy perhaps your favorite clothing, hoodies, turtle necks, booty shorts. And perhaps giving the shop a hidden agenda now that its so close to the Rack facility, makeing them sell sell sexy costumes and other clothing for your evry Racking needs.
