Ask HN Mods: Can we add some extra options to comments?

In large threads where there are hundreds of comments, I find myself frustrated at times with the way comments are displayed.

1. They don't seem to display in order so new comments coming in can appear anywhere making me have to scroll through all the comments again just to find the new ones (even with browser plug-ins that highlight new comments).

2. There is no way to just view top level comments (yes, I have a browser plugin that allows me to collapse comments, which I think HN should do on its own, but I'd have to manually collapse each one just to read the top comments). Ideally I'd like a fast way to view all top level comments by default

Some threads where this immediately becomes applicable are threads like "Who's Hiring" and "Idea Sunday", etc... I'm sure there have been other popular threads where comments just grow out of control and I wish there was a better way to manage this.
