clubman, SimonBRT & others - when describing proposed improvements to the layout its best you post a screenshot of at least what is wrong with the current layout for you, and better with a mockup of what you propose.
Its quite hard to understand exactly what is meant sometimes and also as you might guess there is a large variety of screen sizes, how big people have their artwork saved and lastly its sometimes not clear if you are refering to when the Track and Artist panel is docked in a tab or bottom of the main panel which affects the space used. Also album pictures are usually square where as the artist picture proportions varies greatly.
i'm only willing to change the proportions, not the panel arrangement
