First of all, GREAT JOB. I am very excited with how quickly this scene is taking off. If I had coding knowledge I would be helping but instead have to sit and watch.
I don't know if you are accepting requests at all? I have children that use my PS3. One of the reasons I LOVE being able to backup to HDD is so my kids dont have to handle the disks and lose them all the time. So far all the managers have a shortcut to the delete feature on the remote. It would be nice if there was a way to make the software have a user mode, and an admin mode.
User mode would allow you to boot the game and that is all. After a certain button combination it could unlock admin mode which gives access to add, delete and all those other options. Maybe for now there are other things on your "todo" list. But if you find time to get around to blocking the delete function a bit better please do.
