In BeSocial, hovering the "more" button shows the arrow, "correct".
But it also enlarge the button and moves all the others a little to the left (see attachments).
I suppose you could position it over the "..." on More to prevent the jump, but maybe its not needed at all?. I don't recall what 1.0 had.
In light variant the arrow is shown for a second (till the list is shown) under the button. Maybe that's a solution too?
So far it is the same as this site.
Then lets keep it the same and remove the hover arrow, IMO
Good point. :P
Fixed locally.
