Total_Noob Wrote:Do you have XMB options you never touched? Would you like to replace them with something useful? If yes, so XmbIconManager

This plugin allows you to edit the icon name to your desire and replace options with useful things like:
Load homebrews, updates, psx games and backups, or shutdown, suspend, reboot and restart VSH.
