What are the performance implications of hiding an application window vs closing it entirely?
For example: When using an instant message client, it can be set to open automatically when the system boots, and it will show the contact list. But the contact list can be screen clutter when it's not in use.
Does it waste resources to hide (CMDH) applications? Or would it be better to close(CMDW) the application window entirely, without actually quitting the application?
