Move/ restyle Logout link

Currently plugin works great! However, it’s just a styling issue bugging me.

When logged in, it states “Howdy email”|Logout so everything is kinda jumbled together on one line.

Can anyone advise as to how I can 1) put the Logout link on another line below the greeting and/or 2) make the logout link into a button like the Login link/button is? Thanks!
