1. Color presets. The color picker is a blessing and a curse. I feel like it gives me a little too much control. It can be difficult to get colors to match on a hue/saturation/value level. If at all possible I'd really appreciate a second color picker where it has pre set colors.
2. Sections collapsed by default. It makes navigation a bit more annoying to have them all expanded by default.
3. More hairstyles, pants, and longer skirts! Maybe a slider to edit the length of the skirt, that would be cool if possible so you don't have to have additional entries in the clothing section clutter up the space.
4. The right hand on the hand on hip pose doesn't really look like its on the hip, I think it needs to be a bit higher and needs a subtle shadow underneath.
This software is seriously great, and the art isn't half bad for being vector. I used to use it more often when I went through a VN dev phase however now I just use it cuz its a fun tool to help break my artist block once in a while. Looking forward to what this app has to offer in the future!
