Microsoft Office

I usually prefer using LibreOffice over Microsoft Office because it's free / libre software and I can use it on Linux. However, while writing a seminar paper, I noticed one feature that LibreOffice Writer is missing and that made me use Microsoft Word for the paper: literature index. I need to make references following the IEEE style. While it's pretty easy to create a literature index and select whether it should be IEEE style, APA or one of the many other styles, literature indexes in LibreOffice are a pain.
