Code folding question in mono develope

I was just thinking it would be extremely helpful if you could default whether particular functions/classes/enums were folded by default when opening a file. Anything like the following possible?

public void ThisIsDoneAndIRarelyLookAtIt()  //FOLD BY DEFAULT
{

}

public void ThisIsSomethingImCurrentlyDeveloping()  //UNFOLD BY DEFAULT
{

}
#region CategoryA
public void ThisIsDoneAndIRarelyLookAtIt()  //FOLD BY DEFAULT
{

}
#endregion

#region CategoryB
public void ThisIsSomethingImCurrentlyDeveloping()  //UNFOLD BY DEFAULT
{

}
#endregion

And minimize/maximise as desired.

Thanks I’ve used regions before, but after reading your post I found that you can have them folded by default. Its nice to open a file and not have to scroll through a ton of stuff to fine what your looking for.
