I recently obtained OD+ and am having some difficulty in placing the systray and open windows entries on a tabbed dock. on non tabbed docks there is an option to place the systray and open windows on the dock under the settings dock contents. However on Tabbed docks, there is no dock content only content settings and then you can only chose to either use or not use grouping on taskbars within OD.

That being said, how do you place the systray or open windows on a tabbed dock?
