Well, I was sort of serious: in the sources I read small caps are not only used for Roman Numerals in dates etc., but also place names are often printed in small capitals.
This is, of course, not an essential feature: at the moment I just use normal capitals, which is fine as well. But given the fact that I like to represent the extracts as accurate as possible, I thought I could mention it.
... I am curious to learn why a note-take system looses its effectiveness the more it treads in the realm of word-processor.
