Ok, here are my thoughts on features for future development.
1. Config File Backup. We should have a menu feature that enables us to backup up the config files simply in order to enable a quick restore but without backing up ROMS and actual software application or OS code as well. Should make for a small backup but one which can be re-laid upon a restored image with the minimum of fuss.
2. On the Emulation Station Rom selection screen a feature to check or uncheck the ROMS for visibility in the list would be great and much simpler than hacking around in the actual file system.
