Expanded view of comments

The current view of comments is hard to use because you have to hover over each one to see them in full with the context of where they are placed. I find myself repeatedly opening each one while brainstorming or viewing feedback.

My idea is that when the user hits C on their keyboard (or another shortcut), they can see a slightly expanded view which includes the first comment in a thread and the # of comments in the thread (Screenshot 2).
