The Companion does not support offline actions at this time. This is something a number of users have requested, but that's going to be a lot of work, so I'm waiting until the appropriate time to tackle that. The companion just lets you add/edit your library, and every change you make is transferred wirelessly to the tablet. You can use the companion to wirelessly transfer a backup of your library if you want to use your PC to store the file. Generating .msb files is the best way to backup MobileSheets. To add songs, drag and drop files into the companion app (this is the easiest way).
