You may want to hide certain portions of the header section in an SBM State form . These may include the navigation links, project name and item id, the transition buttons or the actions drop down or a combination of them. The following doc talks about how to accomplish this.
In the various forms used in the Service Manager application like Service Desk, Knowledge Management etc you may want to add or remove transition buttons or move items so they show in the "More Actions" flyout menu. In the example below you may want to move the "Escalate" button so it shows in the "More Actions " menu.
