Allow dynamically updated Forms, maybe via Office.js?
So, Forms is really not that powerful, especially when Google Forms has the power of Google Apps Script behind it.
For example, there, I'm able to dynamically update a Google Form with the latest set of (automatically updated) dates for a user to select any of the upcoming Wednesdays for the next ten weeks.
Forms ... ... ... can have options. That are pre-set, and even the branching is pretty basic.
With decent Office.js support, or at least better Microsoft Flow integration, when we could interact with the data on the form a little more.
Alternatively point to the REST API, or even, I dunno, give it some documentation on docs: https://docs.microsoft.com/en-gb/.
Please, just let us make this more powerful, we're struggling here with lesser tools that simply don't feel as 'modern' as Forms ... and that includes the new SharePoint Online input forms.
