Jim,
This is one of the new interfaces for the new exporter (there are several). It's actually "skinnable" so it comes with about a dozen different user interface skins that you can choose from, each with different features. Here are some samples:

Here's how to apply new skins:

There's also an online "skin repository" that we've started where you can download new skins:

Since the skins are all just HTML and Javascript, any web developer could make new skins. In fact, if you kept the funtionality the same, you could just make new skins by changing the graphics and HTML of existing skins and you wouldn't need to even worry about the Javascript. Ideally, I'd like to see some artistically minded user interface designers building different types of new and improved user interfaces (and hopefully letting us upload them to our public online repository so others could use them).
As far as building exporters for the free version of SketchUp, I would certainly love to be able to do this, but unfortunately the free version of SketchUp doesn't support exporters (or importers) or any kind. So, we can't do much about that - you'll have to take that issue up with SketchUp!
Best,
-abe.
