Hi @Dodo Bird, one approach is to use indexOf() to search an Array for a particular string. ExtendScript's Array doesn't come with an indexOf method, so we can make a simple one. Then I've put the filter into a function that also has the list of excluded names—it might be better to put that outside the function in, say, the script settings where you can edit them easily.
Hope that makes sense. 🙂

Edit 2023-05-04: changed indexOf to a normal function, not Array.prototype, for clarity.
