Nice improvement!
May I suggest that showing all comments in a document is a function (something to select), and a per user setting/option to make this the default.
IMHO, the initial default should be not to show all, for minimal confusion (analog to public comments to posts, you don’t see all the site’s comments unless viewing a comments feed). But a comment count could also be a way to discover them.
You currently have a “Comments” heading (and as menu item under Tools & Options – Plugins), and below that another “Comments” subheading. Not ideal.
It could be “Block Commenting”, then “Preferences”, “Comments (List)”.
Anyway, this is starting to something I will use and recommend!
