No, AFAIK there are no good addon for this. There is a buggy addon by themehouse which has many problems. It appears several times on widget pages.I just tried again and had 3 buttons on the same page. Now after saving the options a few times, removing the widget and restricting the function to forum only, I was able to reduce it to 2 buttons alongside. After some more refreshing I have only one. But I expect it may be gone later.
