While working with GpProfile you'll notice that it has persistent interface - everything you change (window position & size, list sizes, source preview height...) is be remembered for the next run. Therefore it is very easy to use GpProfile in two sizes - one small (to fit beside then Delphi IDE) and other maximised.
Layout Manager is a feature of GpProfile that allows you to use more than one UI arrangement. It is accessible through the menu Layout and through the layout (rightmost) toolbar.
