Hello, User0613.
Unfortunately, there are no Microsoft developers here. On this forum, ordinary users help each other...
I recommend sending all wishes and new ideas about Fresh Paint to the developers by E-mail. To do this, open the Fresh Paint application and go to the "Settings" menu in it, and then select "Send feedback". The default mail client opens with a draft of the message. Write down what new features you would like to see in the app and send an email.
