Offline Functionality for Editing Shared Documents
As a user who goes in and out of network/wifi access, I would like to edit shared documents "offline" that will temporarily store my data locally until I am inside my network/wifi area when I can sync the data back to the master document.
Put more functionality or let us build add in's so that we can use excel online as if it were offline.
This would make office online apps so much more useful. Google can do it and missing feature mean someone else goes to the dark side!
