Well, this was a lot easier than I thought!?
You can now re-arrange the component order through the Dev Console and when you hit "Save" it will automatically update the Web App.
UsageWhen you open a component details in the right corner you will find up/down arrows, simply click the arrow to move the component up/down in the list.
Make sure to press save when you have finished and if you have the App open at the same time with that device details open you will see in few seconds the components re-arrange themselves in the same order as in the Dev Console.
Enjoy ✌️
