The day has come, this feature is out in beta. It looks like this: https://x.com/lachynicolson/status/2023882074701365578
If you’re in Launchpad, our beta group, you can click on ‘App Library’ in the left sidebar and set up your folders. If you’re not in our beta program, make sure you’re in a paid plan and send a message to support@assembly.com and we can get you added today! Alternatively, if you wait until mid March, this feature will roll out to GA for everyone (along with many other new things)
