I would like to modify the W/E by either changing the layout, shape and size of the drop down menus or adding a "ribbon" like in the MS products. Is this something that can be done with the development API? My target is the toolbox right now as I would like to be able to "auto hide" it to clear up more working space and then when an object (wall, window, etc.) is selected the screen would automatically show the favourites in one panel and all of the options in another panel. The idea is to show everything when an item is selected instead of clicking through menus. I'm just not sure this can be done as an "addon". Any thoughts?
