All three ts take notes while in session. It doesn't bother me. I think it helps us pick up where we left off in the last session which is very helpful with EMDR and Brain Spotting. I dissociate so I often don't remember where we ended and I like them being able to recap the last session. They all just jot down a few things, and they don't record their opinions (if they did my curiosity would drive me crazy).
I guess I think that if I need the reminder, it's ok if they do also.
