Block queues for each page - open discussion

Finally someone... the current block management is not suiteable for big sites with lots of writers who want total control over blocks being displayed on which page. Therefor I've been looking for the past couple weeks for a good solution. I think block queues is on it's way there, I though suggest (want to discuss) the following improvements:

- in the config area the admin has to create a master block queue, or a global block queue
- the admin the assigns this block to a region
- when the admin is on a page, there is a little icon "administer master block queue"
- by clicking on this icon he can edit the block queue for this current page
- for displaying -> the module checks if there is something in the block queue, if not it checks with it's parent item and outputs this BQ and so on.

- Hierarchy would be give through the path alias, for example news -> news/sport -> news/sport/ich-bin-artikel

Benefits:
Editor can have the full control over there sites -> that's what they usually want. If they don't want to have so much control, they can just define a parent block queue and have it applied to all the children

What do you think of this idea?
