Make the "drop down" feature of the org selector more visible (actionable)

[vlad-ko]

Customers get confused, because they can't figure out that the drop-down or selector is actually something they can change. We should try to make it visually more prominent as a drop-down selector. The other issue is that on the first login the customer defaults to their personal account. They get lost, because they cannot figure how to change or even that the need to change to the org in top left.
