@saunders some of the posts you link were already published so, it's a bit more difficult for us to identify them and answer. We will catch them up and give an answer asap. Thank you.

@saunders UPDATE: this post: http://forums.b2evolution.net/suggest-add-the-table-of-a-post-content#c109520 is referred to a third-party plugin.

Third-party plugins' support is in charge of their own developers (if they are up to offer it). We often try to help, as part of the community, but those threads are usually less attended.
