Rekordbox Resize Browser Height Pane

I'm using Rekordbox 6.8.5 - please please please add add option to resize the players window height in EXPORT mode (or PERFORMANCE)

Those waveforms are tiny (height too small) on my 4K monitor.  I know I can zoom in vertically but I want to change the height so I increase the height of the box in red and decrease the browser window height (or collapse it):

I note if I switch to EDIT mode, it is similar here - BUT if I press on the Browser tab it disappears and we get a full height view for EDIT mode - although the wavelengths don't increase in height so not as useful as it could be.  However, my request is for EXPORT mode (or PERFORMANCE)
