Afaik it's a plugin.
And there is no possible way the video could have helped others?
Why did you remove the video?
That worked perfectly. I made the line 3px and that separates each post much better.
Is there a way to include the avatar of the poster on the dashboard?
It would be better if you open a new topic for a new question (and rename this topic to something meaningful).
It would not be that easy to add the avatar afaik. You would need to edit the specific template and maybe add a php script to ask for the avatar.
