Something like this;



Hovering above nodes will reveal add-button. Clicking  on the add-button will set node as 'checked'. Clicking on node-text or clicking on arrow will slide on 1 level deeper in the nav. EDIT: 'Done-button' functions to finishes the task 'add nodes' Or click outside the menu (eg in main-section) will hide menu. Good plan?

How to 'select' menu items that also link to deeper items?
The book asks me to make new verbs from the following words: clear, noble, body, rate, store.

For clear, I can use clarify; for body, embody; for store, restore.

For noble, I am not able to think of any new verb. For rate, ratify doesn't just satisfy me because I guess the meaning of rate and ratify are different, unlikely from clear and clarify which still have the same kind of meaning.

I wish somebody could help me with noble and rate.
