How do I add power tools?

What sort of "Power Tools" are you referring to or looking for?

If I am not mistaken I believe you are likely talking about our Widgets and Apps.

If that is the case then you can find and add them to your form(s) after you create or edit a form.

They are found on the left bottom tool bar under Widgets and also on the top toolbar under Integrations which is actually our Apps.

If you meant something else then please explain more so we can assist you better.
