Nintendo has added a new folder-style feature to the Switch’s UI, more than five years after the console was first released. It’s included as part of system firmware version 14.0, which is available to download now.
This being Nintendo, the system doesn’t work exactly like you might expect. It’s called “groups” and doesn’t allow you to place anything on the home screen — instead, you have to scroll all the way to the right to get to the vertical list of all your software and press L. That lets you access or create groups of various games. Nintendo has posted a guide to using the feature here.
