Finder wastes /leaves dead vertical space between details and preview panels
There should be two ways to reclaim 'dead space':

drag column width (works only on separator between 'Name' and column next to it; 'Name' column width 'consumes' dead space width)

drag Finder window size (right side) smaller (size reduction starts at expense of 'dead space')


In both cases in order to work pointer must turn into &quot;arrow left and right&quot; (↔)
