A feature I'd like to see

In Visual Studio .NET it's possible to define your own code-folding regions:

#region Network communication code
public void myMethod1();
{
....
}

public void myMethod2();
{
....
}
#endregion

I'd really like to see something like this implemented in IDEA, perhaps like
so:

// @region Network communication code
public void myMethod1();
{
....
}

public void myMethod2();
{
....
}
// @endregion

... it's amazing how being able to organise blocks of code and then fold
them away can help.
