Backup Songs to Cloud

Dear team, charts has been a great app in helping me organise for my worship setlists for more than an year. However, there could be a few additions to it to make it better.
1. Allowing users to backup the songs to a cloud service(Google Drive, Dropbox) which helps us in accessing content incase of losing access to our devices.
2. It would be good if there were much more customisation options (Chord diagrams, Text and font styles and colours) added right in the edit sections.
Hope that you will work on this making charts a great app to work more!
