This was the point I was making below, but it seems like all of the features I look for are already in Visual Studio.

I'm not sure if I'm understanding all of your items exactly, but I just tried to do everything on your list. It seemed like each (except for acronym completion) was available right out of the box (I am using VS2013).

For example, both the class view search and find files are handled by searching solution explorer. It updates in real time and the keyboard shortcut is Ctrl + ;
