Welcome to the Community Forum @Louis_Cornacchia!
These are great questions! It’s currently not possible to create more than one form per project. We have an existing product feedback request for this feature Allow to have multiple forms attached to the same project , I recommend you to upvote.
We have recently launched a feature that allows you to duplicate forms. This means that when creating a project from a template which includes a form, or when duplicating a project containing a form, this form will automatically be copied over and generated into your new project. Although is not possible to move a form to an existing project, you can create new projects using your template form.
Lastly, you can find your forms when accessing each project but we don’t offer a forms library. I recommend you creating a thread in our #productfeedback category to allow other users upvote for this feature.
I hope this helps! Let me know if you have follow-up questions
