So I did some CSS inspection last night and could adjust things to resolve number 3, I could somewhat resolve #2, but had alignment issues with non-dropdown entries and the arrow still appeared on the next line.
it seems as though the dropdown submenus have an extra padding to the left, and I have not been able to enact any change to the down arrows beyond just disabling them.
I can show my code if that would help but the html output looks clean to me.
