1. Default Section

* 1. I have a tree structured UI that displays 'things that can be enabled/disabled' as nodes. You can trigger an action against a node by selecting the action from a 'right-click' menu.

* 2. If multiple selection of nodes is preferred, how would you deal with following situation:

The user has selected multiple nodes. Some of them are enabled and some are disabled.
