The latest release of Sidewinder includes an editor with colour-coded syntax highlighting, and an XForms events viewer.
You'll find links to the download, and information about these and other changes, on the Sidewinder project page.
The features are available when Sidewinder is running in 'Standalone Browser Mode', which is explained in more detail in the Sidewinder handbook.
To make use of the event viewer you will need at least formsPlayer 1.5.0.1022.
