How to retrieve and list local charms in juju-gui charm browser?
Solution 1:
In order to get your charms to show up in the charm browser you will need to push them to your own namespace in Launchpad. Less than 15 minutes later, assuming charm proof passes, you'll be able to see your own charm in there.

Just FYI, there is no technical difference between dragging from the Charm Browser and dragging a zip archive of your charm from your machine.
