Summary

We can see that there are many use cases where a simple UI can at least simplify our work with spreadsheets and documents, either by showing data in a way that is not directly available or by adding extra functionalities.

We can also use the UiApp service or HTML service to create UIs; the latter allows us to create more fancy user interfaces if we are using third-party libraries.

Of course, this means that we'll need to learn a lot of new techniques. The complete documentation about jQuery is about 300 pages long (http://forum.jquery.com/topic/jquery-1-7-reference-documentation-as-a-pdf), and I'm not even sure that reading it entirely would be sufficient to use it easily. However, as we shall see in the next chapter, the learning process can be gradual.
