Could you reduce the size of those Preview (frankly) thumbnails, they're way too over-sized. Something like the other buttons would be fine.

Could you add the option to remove, click read or something to the Best Practice-advertizing in Preview window? I'm fine with seeing the new knowledge once, but having it appear every time I Edit, without way to remove it is annoying.
