Backup/Restore Option for categories, moved apps

Please add a Backup/Restore option so you can save and restore your categories and apps moved to each category. Would be useful if you uninstall the launcher and need to reinstall it or move to a new device without having to create everything over again.

Perhaps it can save to a file that you can copy somewhere(Downloads folder) or use cloud storage like Dropbox to access the saved settings file? Not sure if newer Android OS's can let apps access files not in their own directory but maybe it's possible.
