Stage Manager (Ventura) and resize/center a window

I resize (90%) and center a window on my screen including the dock and bar in calculation. Using Stage Manager the center of the screen shifts to the right and the size changes for the calculation of a new window (90% of the screen). Is there a way to include the space on the left for stage manager in de calculations for center resize a window.



Ah I need to add an option to exclude/include Stage Manager in the calculations.

For now you can only change it for all windowing actions (the leave gap option):

ok; I will wait for the new option...
