UI Layout

Hi,

I am currently trying to learn how to create addons for blender with python. My first project is going to be creating an exporter for a somewhat obscure games engine.

In doing so I need to get the user to configure there blender project in a specific manner such as specific scene names and custom properties etc.

My first problem is:
I want to create a panel in the properties window under the scene tabs. However, I would like it to appear as the first panel to appear eg [MyPanel, Scene, Audio, etc…]

Taking the simple panel demo what modification need to be made to get it to appear at the top of the tab?

Please note I have spent the last 2hrs going through the api documentation and as far as I can tell there is no way to do this other than have this scrip run before scripts\startup\bl_ui\properties_scene.py

Any help would be greatly appreciated.

Thanks

        layout.label(text=" Simple Row:")
        
        row = layout.row()
        row.prop(sc, "frame_start")
        row.prop(sc, "frame_end")
