At the moment there are 72 extensions. Given a large number of Docker images and use cases this seems like a rather low number to me. On the other hand some of the extension have a large number of installs, e.g.. Disk Usage 280k installs, Logs Explorer 74k, etc.
Do you use any of the extensions and for what do you use them?
