For those who edit the shellstyle you know what a mess it is in there. To format it to a regular XML layout so you can understand it better I recommend
Kaxaml.
Just open the program and drop in the UIFILE and on the left click on Xaml Scrubber. I use the settings [Disabled, All on one line, Checked, Unchecked, Unchecked] though you can have whatever you prefer.
