"Facebook-like" Alerts are a huge win in Xenforo. They just work. Obviously people like the Alerts .. so vBulletin copied them ... but vB's implementation just doesn't feel the same. Implementation is everything ! I was just browsing google news today and noticed their new "hover over the title" dropdown popup ! It was discrete (not visible before hovering) but quick to popup when I wanted it. Just like Xenforo alerts .... it just works well. This could be something to emulate for "Thread tools" in xenforo.
