Geotag management: allow changing/adding/removing geotags of (ideally) any file.

Excellent suggestion. Also, it would be nice that the OneDrive API provide an ability to add lat/long geotag information similar to what Flickr does. This way, applications such as geosyncr.com can connect to OneDrive and geotag. It would be nice also that the data be saved back to the file metadata EXIF/IPTC accordingly. In a similar fashion as in Windows Photo Gallery.

Have Onedrive retain and maintain the functionality the geotag that I placed using Windows Live Photo
