Hi Petri,
You can already create a similar start menu with the SR6 release. Simple add all the All Users applications that are in you example on the top to the root level of Application Management in RES PowerFuse. If you want to get rid of the RES PowerFuse Settings menu, disable this in Lockdown and create only the required items in a sub menu in your start menu. Here is how to do that:

I think your can create a start menu close to the one you have right now. Good luck.
