Feature much needed

Hello to all

Anyone know a way to set/scale the dimensions of the 3D window to a
desired value, let’s say 800x600 ?
It’ll be very useful to test/target games ( or even renders) to a desired resolution?!
Thank you
Bye

Oto,

you could start blender with -p option (e.g. blender -p 10 10 500 300). The (saved) sizes of the views should be proportional to the application window. But the menu bars seems to have always the same size.

Maybe this helps.
