[ATarman]

Reference the solution in the link below to allow resizing of the System Explorer window:

This is very helpful and would only be better if it was possible to adjust the vertical pane [red arrow] horizontally to make the right side of the window wider.  I was not able to find .ini syntax to adjust this.  

Any recommendations?
