"Find Usages" enhancement

[LittleBigDev]

Hello,

Do you plan enhancing "find usages" feature ? For instance, when I'm looking for a model class usage, I get no result because any use of this class is made via Mage::getModel() It would be awesome if I could use "find usages" on my model class and it would return me all related Mage::getModel() calls !
