I believe we have needed for several versions now, a much improved WYSIWYG A5w page editor. It is extremely difficult laying out navigation buttons, grids and text on the current page. Something like the Yahoo Sitebuilder program would be perfect! In that program, one can simply choose the component and set it onto the page and it renders exactly as it was laid down.
How about a save & publish button (2 in 1) when working on a component. Will just make it easier when you want to do both and sometimes the save button doesn't register when you click to publish so you have to re-save then publish again.
