i keep most windows in fullscreen and use the expose function or how it's called that shows all windows in reduced size to switch. sometimes i put two or three windows side by side if i need to see them at the same time.

i also make use of multiple workspaces/desktops to arrange windows that are related to each other.

so i use the maximize function but never feel the need to minimize windows unless it's a window that i don't need to reopen ever.
