Difficulty creating an XML file using the Wire Editor.

I think I may have found a bug. I was having difficulty creating an XML document within a folder for one of the tutorials. It would allow me to create a file, but the ".xml" suffix was missing and the editor didn't know that it was an editable file.

I then created an FTP connection and manually uploaded an XML file that I created locally on my computer. After doing so, the editor recognized what type of file it was thus I was able to edit the file.
