Now if you want to be even more impressed, go have a look at the issue tracker page (https://code.google.com/p/google-apps-script-issues/issues/list). This is not only the place to drop the issues you are met with—although it is good to know and very useful to read as well—but it is also the place where users can place their enhancement requests.

Also, there are so many enhancement requests in so many fields that I guess they will probably never accept and implement all of them. However, I know they are very attentive to it and consider each of them most seriously, and evaluate their usefulness and feasibility. I know that we are going to be surprised by the numerous features they will add in the coming months, not to mention in the coming years!

I said earlier that learning Google Apps Script is a never-ending process, but I'm sure that developing it is even more endless.
