switching modes

we're playing with one idea to switch between two different areas of the application, with different interfaces, each best suited to the task at hand. so organizing your fonts will have a different interface than browsing your fonts.

do you guys think this type of interface element means that it has to be relative to the context, or could it be a switch for the whole application? meaning, if you're in a collection but flip this switch, would you expect to be organizing this collection, or would it be fine if after you flip this switch, the interface changes completely to a different setup?
