Does anyone have color / font / intellisense for editing NSIS files?
You can edit the usertype.dat file for syntax highlighting, but it is better to use an editor that supports NSIS files (any Scintilla-based editor - SciTE, Notepad ++, Notepad2)
Not tested, but it probably does the trick: http://visualstudiogallery.msdn.microsoft.com/5e57fe9a-ae5d-4740-a1c3-7a8e278e105b
