Save the screen position for the "Login" window

When pressing the "New session" tab a "Login" window will show up, but it will always be centered on the screen. I then have to move it every time because in the lower part of the window I run OSK (On-Screen keyboard). I want it to remember its place when I close it, so it will open at the same place next time I open it.

Something I noticed is that it does remember its size.

Thanks for your suggestion.
I will see, if more people ask for this.
