A: Hi Sumo-ling,

Thanks for your question.

Indeed, the Unified Inbox (responding to comments / messages / etc) is already in the works:
https://trello.com/c/GhXX4f3R/74-unified-inbox-for-comments-and-replies-community-management
I can't yet give you an exact estimate to when it will be completed, though, but it should be in the next few months.

Regarding reports - we have analytics and a weekly analytics email.
More branded reports will come later (it's part of our internal roadmap).

I hope this answers your question, but if not, please let me know.

Bee safe,
Ovi
