I attended one of your training sessions recently. We spent a bit of time on debugging, but I almost think there should be a class devoted to it. A 1-2 day class going over the Chrome and Firefox debuggers, as well as other techniques used. A problem I had today was solved via the forum, just by changing which ext class I imported in. Tips such as this could really increase productivity. If not a class, maybe some webinar sessions would suffice.
