1) Custom components: This feature is comming soon, we had technical limitations keeping us from adding it, hopefully it will be added by 5.0 GA, but not sure yet.
2) Order: I don’t think so.
3) A divider can be added to your form using the “H” looking control for JSeparator. If you mean a divider or folder in the component tree, no. The closest thing you will get to a “Folder” is to create a new JPanel and place your components in it. But keep in mind, this is not an organizational construct, this will also effect how your form is actually laid out.
