Priority organized buttons for the most important aspect of every function. All I want to say is, it is waaaaay to much searching in the menus. You get lost, and it's way too much time spent in searching for a function, or to change the element as you really want to be. It has to be more intuitive than that. Make a command line, both for functions as wall, slab, etc. and in the properties of an element, so that if I want to change the height of the label of a door, I don't have to go trough this labyrinth every time.
