Hi @CAdams21 & @HelenPantel! At this time, seeing a full list of attendees (including external contacts) isn’t on the roadmap, nor is more functionality around logged meetings. The product team is aware of this feedback, and I’ve shared it internally. If anything goes into development regarding either aspect, we’ll be sure to update this post. 
In the meantime, a possible alternative would be to schedule the meetings instead of logging them, but I understand if that may not always be the ideal option. I just wanted to mention it in case it helps, as the product team highlighted scheduled meeting attendees can be reported on currently.
