Hi Tony,

That sounds like it would work well.

The only thing is that I'm not so sure yet if you really will care that much about knowing when something is "hidden but locked".

That's why I was thinking of making both "hidden and locked" as well as "hidden and unlocked" just be blank. That lets me have just a big lock icon for the "locked and visible" state which may stand out a bit more as compared to a lock in the corner type thing.

I think I'm going to give this "3 visual state" thing a try at first and just see how it works in practice. If that does not work out then I can switch to a 4 visual state type thing like you are describing.
