I couldn't find a field that I was looking for today, despite searching for it specifically, because it was hidden inside it's parent object. I understand that the reason for this was something to do with there being no difference on the field (and I appreciate that the reason is to avoid clogging up the screen!), but if you're searching for a specific field, I think it should really show up...

Took me bothering someone on live chat to figure out what was going on.
