developing a control panel system

[eluser]AtlantixMedia[/eluser]
Hello,

I'm developing a control panel system and was wondering what would be the best way to go about it. Ideally, I would like to have sections as:

My Profile
My Ratings
My Favorites
My Comments
My Buddies
etc

now I want to make this in such a way that I can use the same system with different projects. Of course, not all projects will need a My Buddies or a My Favorites section. what would be the best way to approach this:

1) have one controller MyAccount with different functions for each section and use re-routing $route['My_Ratings'] = "myaccount/myratings";

OR

2)have one controller for each section of the control panel

thanks
