I think it'd be great if PowerApps could connect to PowerPoint, and you could import existing slides into an app.
For example, to put content into a PDF Viewer, I'm currently creating slides in PowerPoint, converting them to PDF, and uploading them that way. This adds extra headache when I update something in the PowerPoint because I have to create a new PDF. It would be great to be able to "refresh" the PowerPoint data source, similar to what you can do if you update information in an Excel table that's connected to an app, rather than having to create new PDFs every time I make a small change to the content.
