The dialog "before", with some changes,
The buttons are aligned horizontally.
The checkbox are aligned horizontally.
And the space regions got aligned horizontally and vertically.
The path textbox is wider.
The buttons should be regrouped,
having the same width, same height,
same size, centered vertically/horizontally by matching
the square box and other vertical lines in the dialog, if possible.
Also, more keyboard shortcut should be provided. The first character should be capitalized.
