homebox

Hola a todos,
Tengo que crear una dashboard para cada usuario.
En el dashboard un usuario tiene que ver todos los nodes del Content Type "ToDo List" creados.
Ej.
-List A
-- Item 1
-- Item 2
-List B
-- Item 3
-- Item 4

Las dudas que tengo son muchas:
1. Los Items del Content Type "ToDo List" es mejor que sean "terms" o "nodes" ?
2. Como puedo ver todos los nodes "ToDo List" que un usuario ha creado ?
3. Es posible insertar cada nodo "ToDo List" en unos bloques? (asì que puedo utilizar el modulo "Homebox" para visualizarlos).

Muchas gracias !

I am using Homebox module for creating a Dashboard. I created a view as block so user can add it in their Dashboard multiple times. I added the Exposed filter of taxonomy terms and I entered the choices of user in my custom table. Now user can add same block with different choices. My questions is how to manage different choices with blocks, exposed filter have same id on each occurrences.

I have an idea and Im not sure if its possible with existing modules or if I could create something to do what Im looking for.

The challenge:

Im looking for functionality much like the homebox where a user can choose from pre defined blocks and build up a dashboard, but heres where it gets interesting, I would like to integrate this into a User specific menu where a user can add remove and move around the blocks in a region like say the second sidebar and this user menu would be on every page as they browse the site.
