Comment Reader Needed for Blogger

Few people read my blog, and slightly fewer than that comment on it. So I don't read comments regularly, though I do make it a point to catch up on them. And when I do, I always find myself scrolling through lots of posts, finding the few that have comments. Every time I do this, I find myself thinking "there must be some kind of comment-reader utility in Blogger".

This time I took a little time to search. I think I found the closest thing, which is the Moderate Comments option in settings.

What I am thinking of is a kind of view that would make it very quick to see only my posts that have comments, and to read those comments. I think the ideal would include:

1. A running list of posts, with the comments below.
   
2. The post itself would be presented in outline form (first couple of lines, then the rest collapsed, uncollapsible via a quick "Ajax-architecture" plus button.
3. Something similar for the posts, though the unit for them might be 6-10 lines.
4. A way to "Mark As Read".
