Papers: Finding lost articles

Here's something I do a lot.  I'll read an article, quote it in a document and then forget where I quoted it from.   Then I'll have a rummage, fail to find the document and have to remove the quote, undermining the argument I was trying to build.

This happened to me this morning and I had an idea.  Perhaps Papers can find it for me.  The quote was:

" However, most Yers ...".

I selected "Papers" at the top of the left hand pane to bring up all articles.

Then in the search box typed my quote:

And up came the relavent document:

I was then able to click on the document and find the quote that I had highlighted previously.

This may sound like a trivial task but I can see that this would also be very useful when checking the validity of quotes when proofing a document.
