I did see the UML-class, but that was overly complicated (for my

The definite answer is no, there isn't any such currently.  Making one
could be either trivial, simple, or difficult, depending on what you want.

If you just want something like the 'Comment' field on the UML Class,
that's trivial.  It's a text property that's not displayed.

If you want to be able to have an arbitrary number of such fields, there's
either the multi-line text field that a few objects use, or you would have
to do something like what the UML class does for operations, attributes etc
(for which a generalization has been worked on, but not much new recently).

If you want to be able to add different types of properties, like boolean,
integer, text, multiple selection etc, you'd need something that interfaces
with the properties system in interesting ways.  That'd be work.
