Ability to undock the comments list
Ability to undock the comments list and view it horizontally.
There are cases where the comments can be really long, and a vertically orientated list makes it really difficult to read, not to mention the comment may even take up the entire comments pane. Sharing the same screen space between bookmarks, the actual content, and the comments list makes everything less readable. Users should have the option to undock the list and view it anyway they like.
