Subbar as a newline of Default bar

[DrShark]

Currently TC can only either switch to subbar hiding default one or show subbar as a drop-down menu on default bar. There is also a suggestion to make TC show several bars together.

My suggestion: in the button options in addition to "Show as menu" setting add also "Show as new line bar". Click on the such button which refers to subbar will add a new line under default bar with buttons of subbar. Click on arrow button which currently switches to default bar in that case will just hide this new line of buttons.
