Improved synchronization of MS Office apps between online and desktop versions
Files often become out of sync even when opened by one person.
I have a file that is said to be locked by myself when I have sved and closed all desktop and online versions.
Results in wasted productive time and extra files and memory usage when a new file must be created to replace the file that is "stuck".
Better editing of files online might eliminate the need to download onto desktop (e.g. graphic files do not render the same online as on desktop)
