Here's the first release of eZDebug.

The functionnalities of this extension are to browse dynamically the debug of eZ publish. When you are developping you can have a lot of issues in one template and loose time seeking where is the problem. Of course, you will look at the debug but if there's a lot information, you won't be able to find it quickly.
So you can do it clicking on the right corner of Firefox or doing a CTRL + SHIFT + Q.

Another interesting functionnality is that you can flush the page, cleaning the debug. You just have to click on the clean checkbox and then the Go button.

You can also filter on the type of debug message you are seeking.
The next step it to do the same for the attribute(show) operator. It already works for a attribute(show,1), but I except some problems to create several levels in the tree.
