Want the ability to import shapes like you can in the desktop version of Visio. Or be faster about adding shapes that are requested (like AWS shapes). You added Azure shapes, but we also use AWS. draw.io has both AWS and Azure and I am forced to use that program due to I am using a Mac (no desktop Visio) and Visio Online doesn't have AWS shapes.
We are using Visio to document complex network scenarios. So it is very important for us to import third party shapes from network manufactures. As a MacOS user I am looking forward for this feature!
