File upload for flow and flow pro. Google is doing it really well in my opinion.

Forms must have the option of the user who is responding the form to perform file uploads

The users should be able to upload the file and this should be available as a link in the form responses to be visible to the form owners.

Adding upload pictures and document feature, would be brilliant
Teachers and professors could collect the researches and much more easily

First of all, I love the new Forms Pro app, especially the use as Voice of Customer app. For these purposes, it would be quite essential, to use piped data not only in survey email, survey header and questions texts, but also into answers as default to be confirmed or edited.

E.g. Q: Could we call you {{Salutation}} to your mobile phone? We have this {{mobile}} number in our records. A: default/prefilled/piped text would be {{mobile}} from custom data...

This could hugely improve usability of the forms.

It is recommended to add the option to upload photos and upload attachments (the photos are inserted in the excel form, and the attachments can display hyperlinks in the excel form)

Instead of creating a new form for every class scheduled, create a number of template forms that can be opened, modified, personalized if necessary before sharing.

We make email templates for repeated emails, we make word templates for repeated items, why not forms?

ability to e-mail user's responses back them, of course the user has to put the e-mail as on of the questions. Also a way to put this at the end of form. "A copy of your responses will be emailed to the address you provided." MICROSOFT FORMS MUST be better than Google forms/surveys! Google forms has that option. See example.

It would be really nice to have a built in progress bar so people could see how much of a survey they have left

The owner is able to customize the response page and how it looks. Be able to choose which graphs. Also better way to view the details. With the option to include the date and time the responses were filled out.

add upload attachment for uploading a document, image, etc...

So users with free Microsoft account or Office 365 personal & Home account can create forms and use it in work and life.

It would be nice to have a drop down box for users to be able to select one or more choices instead of having to look at a long list of options. It makes the survey appear longer than it is and crowds the page.
