When you choose to take an existing loop and continue to build on that and start to work in it with your participants, then, of course, you develop the content to your liking. Most likely you will want to keep this new and improved version of the loop. You do that by clicking the button Save a copy of the loop. If it was originally your loop, and not one you started from the library, make sure to adjust the name of the loop so you don’t confuse it with the original loop in your list in My loops, where it will end up once you have made a copy of it.
