Can i question why that's appeared there? As far as I can see it is a pointless list of stores which is of no use to a buyer or to a seller.
Which if you click on it, causes browsers to become non-responsive while it builds the list, wasting time and causing IMO a bad user experience.....

The new 'Cart' button has appeared shifting everything left one.
I keep clicking 'Stores' instead of 'My Store' lol
The new 'Cart' button sounds good.
Or if you want to make your store feel really small, sort the store by 'Items' tab and wonder what 4.8 million bricks in one store would look like.
Seriously: I would prefer new buttons to be added on the left side, so nothing shifts...
