Thanks for the screenshot. I see what you mean. In the designer the header text is left justified w/ no left margin. Yet when leave edit mode it changes adjusts to its natural left margin and style. That is a quick in the edit mode that I will open a but on.
We have talked about making the header text position more like some other components that manage text style and layout by using a landingzone. All LZs can be toggled on/off using the snap button on the toolbar or momentarily while holding down ctrl key when dragging a component. Such a mode for a header would enable you to reposition header text anywhere in the header area. Or you could snap it back to default position by enabling snap mode.
An alternative would be to provide a simple left margin property.
