Thank you for the fast answer @pelaird. Since i am not dev youre maybe right. It can be a limitation of Windows 11.
But i currently use the ExplorerPatcher from Github on my other PC.
Link to software hacking Windows system files is not allowed. Removed by moderator.
And there it is possible with patching Windows 11 explorer.
So my wish is that you maybe can implement this also in Start11 cause i want use 1 software.
It would be great when the devs can take a look at it and maybe implement this in Start11 
Many thanks.
