The Grid / Layout manager is a good idea* but it's not very intuitive or customizble
 

I like the grid / layout manager* but there should be WAY more options* particularly WIDTH of columns (not percentages) and some better labeling.

Example:

I want a 3 col setup with a 1000pixel width on the full content divided into 800 x 200 x 200 respectively.

I can't seem to do this with the Grid Layout Manager* there are only a few options and they are all percentages?

Also using the YUI Grid and CSS for that is a nightmare. Who decided to use that?

Why not just have the CSS in one location so we can edit everything / anything we want?

Just a recommendation to improve this and the CMS would be far more useful.
