Add support for Google Drive in Places
So far it looks like only local, One Drive and One Drive Pro are supported for opening Visio files. As a heavy user of other online services as well, adding support for Google Drive, DropBox, etc. would be really useful. I suspect you can integrate these from the application's own sharing APIs (i.e.: if Google Drive is installed, you get a hook for it).
Yes, please! I use the Dropbox connectivity on the other Office for iOS apps (excel, etc.), and it works very well. Please add to the Visio app.
