I have yet to use it, but Dropkick looks promising.

Whoops, I'm so sorry! In the past DN has always warned me about duplicate content, but this time it didn't so I thought it was okay. I'll start checking the Recent Posts.

Having a toggable spell-checker would be swell

I've been using DDG for a few years, and the !bang feature is one of the most useful features of any other search engine I've used. Being able to search almost any other website instantly from one place is incredible.

I can search Amazon (!a), YouTube (!yt), StackOverflow (!so), Google Maps (!gm), and so many more with just a few key strokes. Even sites that I'm not 100% what the !bang is, I just take a shot in the dark and it's typically right (recent example is !e for Ebay).

Integrating it into your URL search bar (I use Firefox), you can basically search any site by just opening a new tab. It's an amazingly useful tool that I use numerous times throughout the day.

Piwik is a great analytic tool

This is awesome. I've been looking for a good stock video site with appropriate licenses.
