The classification of the previous page on the Matches tab can be displayed for some time with no indication that a new classification for the current page is going on in the background.

Really minor; doesn't seem all that slow, but other kinds of classifiers/pages could take longer potentially, so it's a good thing to resolve:

Helpful GIF (hopefully):

I think this is a great suggestion. We need to have the current-page source change the status to PROCESSING immediately when the callback comes in. Some of the delay, however, may be from the process of walking the dom and concatenating the string values in the content.js script. We may need to break that into two events. One announcing that current-page is about to deliver a new value and a second that delivers the actual data.
