Does there exist a Google Apps Script that lets the user rename multiple files at once using a specific syntax?
Like "delete part X from the filename Y of all files in folder Z" or "change strings like "one", "two", "three", ... to numbers like "1", "2", "3", ...". 

For example, in the folder "Stories", all filenames may be be like "Book 1 Chapter 1 The Beginning", "Book 1 Chapter 2 A New Chapter", and I could want to remove the string "Book 1 ", so that all filenames will look like: "Chapter 1 The Beginning", "Chapter 2 A New Chapter". 

I'd like the Script to have a Graphical User Interface with input fields, buttons, lists, etcetera so that I can manage all [the names of] my files using just one Script.
