How to setup grid when the program starts up?

When I start Nvil3d the grid is small and far away
where can I set it is maximized

I do have a shortcut setup Best fit all views.
but when I start I need it maximized already.

view size is setup at 6 and 4 meters...but I am setup in mm

Also where can I download the darker theme I see on youtube?

Tnx!
