Ok, this is what I have changed:
1. Added Unanswered Posts under Quick Links, showing posts with zero replies inside the last month.
2. Can now upload docx, xlsx and zipx.
3. Added Code button to Quick Reply.
4. Fixed Security Token error when using "Mark Forums Read" under Quick Links. It now works properly.
Regarding the other suggesions:
a. Why do you want a list of Moderators?
b) I do not want to close threads. This will deter people from adding to them or perhaps even reading them, in my view.
c) I do not want [Solved] on posts. When I've been to sites where I've been harassed to say if my thread is solved or not, I found it added friction to my user experience. I want this site as friction free as possible.
