What's not in the paper but I find quite annoying in scientific articles is excessively loaded notation. Some variables get to have like 4 or 5 subscripts and equations become unreadable.

I really appreciate when papers get to say at some point "for the sake of clarity, let drop this or that notation" that are not that relevant to the key ideas. Usually it's in the good quality papers.

You mean you didn't find the triple-curly Greek xsi letter intuitive, even when subscripted with mu-nu, and superscripted double prime??
