The groupbreaks just separate out the columns – So if you want to move something next to a groupbreak it would just be the first or last rule in a column (i.e either side). I’m not sure what you’re referring to when you say “new” though! Last I saw of it Andy had said it would have to be custom code.. Can you elaborate?
If you are talking about squeezing something in next to the topic icon, you might need to widen the column. Be careful as that can have a knock on effect to the other columns. Aim for about 99% width overall!
As to the stats under the breadcrumbs, I would have to have a play around locally before posting a method, won’t have a chance to do that until later. Maybe Andy or Steve can point you in the right direction, if not I will take a look..
