I show Cross Hotbar 3 (Left) with both of the expanded trigger controls, so you can easily add in another 8 actions if you prefer, I use XHB 8 as a shared bar between all classes for traversal and general actions outside of combat. Role actions are consistent among my layouts, and so are general actions. The macro icon is a placeholder for a Tincture/Gemdraught.
