Project with many panels

Hi everybody,

I’ m trying to code an application with a lot of menus (9-10).
It’s possible to make this with panels and to bring in front or back.

But, for me it’s difficult to manage many panels, i need to move them for add controls and code. I spent m’y life to find good panel add and replace it.

Do you have tips for this problem ?
How to navigate in many panels and add controls without moving their position.

Thanks
