@trendoman, that column, in addition to showing comments count, is also used to show drafts count. Therefore, it cannot be removed only on the basis of comments.
Not long ago trendoman asked
How to add 'Unpublish' to bulk actions? It is handy to be able to unpublish old blog posts (e.g. after sorting list-view by date), or search results (e.g. pages that contain 'hotel' in title).
I think it really is very useful. Can it be done?
Thanks
