Ability for speakers to edit submitted questions & respond directly to questions via text

Currently, in order for a speaker to respond via text to a question submitted by an attendee, the speaker has to respond in chat.
This is a bad user experience because attendees have to switch back and forth between chat and polling to see the question and the response.
If we use the threaded chat feature, questions and chat will be combined and anyone will be able to respond to the questions, not just the speaker. Plus, it's important to keep questions and chat separate so nothing gets lost.
Finally, I believe the speakers cannot currently respond via text to questions submitted because we're really just hijacking the free-text polling feature.
Please create the following:

• Ability for questions to be moderated
• Submitted questions can be edited by the speaker
• Once a question is approved by the speaker, it will appear to all attendees
• Speakers can respond to submitted questions directly via text before, during, and/or after a session.
