Adding the section describing two advanced GUI applications for managing WINE.
I like your writeup of this chapter. A few comments inline for style fixes, nothing major.
See example 9.37 on how to pull up the "<link" part to save a bit of space in that line where the URL is. It's not wrong, just a tip.
There are < and >'s here, which can be replaced by < and >, respectively. Is that your editor doing that? You can do a sweep over the whole document once you're done and do a search & replace for these.
No indentation within <screen> tags, see section 9.5.9 of the FDP primer.
Unindent this section here as well.
