[Pedro Bessa]

Firefox has getElementById, insertBefore, setAttribute, removeChild etc 
to position, add, edit and remove interface elements. If Unity uses XML 
DOM, documents app creation starting from overview, going to details 
with examples and gives credits to app creators, since changing the 
platform with apps is interesting to programmers, Unity will bring in as 
many ideas as Firefox brought in.
