The UI of app inventor made with GWT you need to take look at appengine folder >> Ode.java

UI is divided into small small parts so probably you need to explore more into appengine folder.

Its so easy to make panels scrollable, no need to modify java files, just add the calc property to whatever you wanna make scrollable

Sample :

height: calc(1000px - 200px);
overflow: auto
