I realise this but I would benefit from being able to see them all in a more compact area.
The crop pane is going to be using a smaller area in the next version.
The histogram needs to be at least 256 pixels tall in order to show you all of the data.
The zoom controls could be slightly shorter vertically.
The Info Text height is adjustable by you. Have you tried making it shorter?
Do you have the Preview window maximized?
That said, the next major version is going to have at least one more pane so unless you really shorten your Info Text you'll have to get a taller monitor if you want all of the panes to be visible.
