[feature]Upload/send files?

Hi jeff!
Thank for your wonderful plugins, clever and well coded!

I’d like to try this one as my go-to form.
Upon first inspection, the only feature I would need that seems to be missing is for the user to be able to send files (zip. doc, pdf) to us through the form itself.

Is there a way to do it, or is it a feature we can expect in the future maybe?
Thank you!
Andrea
