> Now, what if I want to use Calculator to calculate something related to the webpage or code I am viewing

Just type your equation straight into Spotlight and it'll give you the result on-the-fly. Also works for unit and currency conversions.

Ah good plan. My main complaint is the breaking of "normal" window functionality though, not specifically access to calculator - that was an example.

But great idea nonetheless!
