Columns Grid auto size width
I think it would look better if the columns grid proportionally auto sized the columns to fill the available width (so long as it is over a minimum otherwise horizontal scrollbar)
At the moment if you maximise or change the size of the view containing the control you have to manually widen each column to better fill the newly available space to the right of the grid
I hope that makes sense
Thank you for your suggestion. We will think about it's implementation in one of the next versions.
