Didn't see a thread about this - went on PTS to give it a look and I have some comments.
1) Changing a feature and then moving the slider back to a "look" that you already have does not delete the price buildup. Currently, you must click the undo icon to revert the price buildup for that section, which is a little counter-intuitive if you moved the slider back to where it started.
2) Many areas are less than a plat per, while Height and Face Shape jump to around 8 and 15 plat. I understand why some areas would be more costly, but those are big jumps in price.
3) Is there any chance the interface can be modified so that chat tabs are visible while changing your appearance? Or an option to make them visible? Personally, not being able to look at chat would make it difficult, in some cases, for me to spend a lot of time modifying appearance.
4) I noticed that if someone came up to the stylist while I was there, they could block the view of my character. I'm sure this isn't intended. Leaving and re-entering fixed it temporarily until someone new came up.
Other than that, the stylist is looking awesome. Keep up the good work.
