Setting different options for different displays of same view

Perhaps the module does not intend to offer this feature, so I apologize if this is a non-issue. However, here is what I perceive to be a bug:

After defining a view, I have created two different displays for it (block and page). I was expecting to be able to set different options for each of the different displays (for example, include different fields). However, when I change the option in one display, it updates the options in all the other displays.

Anyway, thank you to all the contributors for an awesome module. Honestly I'm not sure why it's not part of the core already - I can't imagine doing any serious Drupal development without it.
