Did not verify all the details on the editor but I had a hard time finding how to change some settings. Some are in the options dailog soma (like the font size) are not. Also I could not change the color coding. As I want to use the tool for documenting I need to copy not only the text but also the formatting. The indentation is set to 1 space where the common is 4. This cannot be changed and makes the readability of the XML very hard. It could be a good tool but I gave it 3 stars for the not so user friendly interface.
