How about a "Live" (or very recent) Status level tab on the URL_REPSONSE probe?
Potentially giving an up-to-date activity level, rather than having to enter each listed URL and clicking the "Test" button.
Doing this after clicking OK to save changes forces a refresh of the whole group of URL's listed, which can take a while, depending number of URL's being monitored and on the specs of the HUB it's installed on.
A live window can assist matching alerts with the current status, as in having the statuses all in one box, rather than sorting an alert window in Infrastructure Manager.
What say you?
