Working with Launchpad is really a joy. It is much more than providing a web interface to Bazaar version control. It also includes provisions for bug reporting and handling, writing blueprints for your roadmap, creating distribution files, and manage your packages if you want to release them in Ubuntu.
Using the above tools, I implemented a couple of new features to MySQL Sandbox, and I started to work on a roadmap for the next version, which is now taking shape.
The latest version (1.22) includes the ability of using a default option file ($HOME/.msandboxrc), a safer usage of the "--force" option, and several bug fixes.
