With the old profiles, when you removed/added a bookmark from the horse profile, the page reloaded. This made it easy to recognise that the process worked. However, with the new profiles the reload is gone (which by itself I think is good! it was annoying) and now the only thing that happens is that the bookmark changes colour. This is quite hard to see when you also still have the curser hovering over it. And the bookmark icon is smaller now. I am always expecting something more to happen and questioning whether it worked.

My suggestion: add a "bookmark added/removed" pop-up, like when you do this action from the bookmarks page (at least compared to live it does that, on beta the functions seems broken currently.)
