im trying to make a visual program of sticky notes and im wondering how i get a yellow box to appear where a user can enter in text.
Try using cp5 library. It‘s very easy to use and has a Textarea object, which does exactly what you need.
would i be able to add each sticky note entry to a dictionary using the cp5 library?
Yes, as the link shows, you can use any Type as value, so also a Textarea object.
