Apart from "hiding" iBliss in a folder can I hide the iBliss app any other way? Can it be locked so it won't open without a password? Can I change the app icon to something else (one idea for "hiding" it if there is no other way)?

There's no way I know of for you to change the icon or hide it--these are things that Apple's iOS prevents. However you can certainly use a password to protect it--just turn on the password option in iBliss's settings.

you should have a look at "poof". you can hide apps with this.
but you need a jailbroken device for this.
just search for poof in cydia.
