Once you start piling a large number of Forms, you might want to organize them in different folders (Categories), for better orientation and control.
Here is how you can do that:
1 - You can always create an additional Forms folder (Category) by clicking on the "Add new" button at the bottom left of your dashboard and choosing "Forms".
2 - Then, you can either create new Forms in that folder, or move Forms that you created in another one.
3 - Rename each of your folders by clicking on the "edit" icon.
