Requesting some features

Just started using this Node Graph and i really like it. I would like to request some features.

1: Node Processing:
          A way to output the result of all connected nodes. You can see this example: http://nodegraph.codeplex.com/

2: NodeGraph Background Grid:
          Instead of white color it would be cool to have grid appearance and the ability to make it toggle to snap nodes on the grid. You can see this example (No grid snap): http://nodegraph.codeplex.com/

3: Node Rightclick menu:
          Ability to right click on a node and add/remove inputs or outputs.

4: Node tooltips:
          Tooltips explaining what these nodes are.
