[Solved]Gnome shell default position for new app window

[chrisyu]

My monitor is 30 inch with 2560x1600 resolution, it a big screen for eyes.
Gnome like to open app window at upper left corner, I have to drag window back to center area of the screen for easy use.

Is there anyway I could customize default position for new app window?
Say, limit to 60% of the screen width, and 60% of of the screen height.

I looked into gnome shell sources, but not sure where to start.

Thanks for any help.

I don't know if you can customise the position but you can center them

In dconf editor go to org/gnome/mutter and check center-new-windows
