Additional option for single screen creation

The option to create a screen in single page by using a splitpane is very good. Currently the edit panel is created in two different tabs which good based on the need. In some cases, it would be more user friendly when the edit pans header and detail are displayed in the same page instead of a tabsheet. We know we can change it easily by dragging the coponents to the right place and delete unnecessary tabs, it would be even more productive if we have an option select use/not use the tab. Pls see the attached image.
