The list includes counting verses and, according to Imam Abu Hanifah's stated view, counting Tasbih on the hand during prayer; the two companions are reported not to dislike the latter in the same way.
It also dislikes the Imam standing wholly inside the Mihrab in the problematic manner described by the commentary; the Imam alone on a raised platform about a cubit high; the Imam alone in a separate ground-level place while the congregation is elsewhere; and a person standing behind a row while there is a gap available in that row.
These are arrangement or distraction issues, not automatic invalidators in every form.
