Everything in Launchpad

This is a list of all the stuff in Launchpad. Think of it as all the features, all the moving parts, all the places where bugs live and where people can get things done.

We can use this list to promote Launchpad, to plan future development work, to be deliberate about what we are not doing and so forth.

If something is missing, add it. Feel free to add notes under each item. Don't worry too much about the categories, they are really there to break the list up.

The more the better. Don't worry if something is too small – add it anyway.

When you're adding stuff to this page, perhaps because a new feature has been implemented, please include the rough date when the feature was added, but only if you know it.


Launchpad Answers provides software projects with a simple way to track and answer questions. It draws on the approach of ticketing systems and bug trackers -- questions have statuses, comment histories and assignees -- but borrows the freedom of forums by allowing anyone to ask or answer a question.

Launchpad's bug tracker is designed for sharing bug reports, statuses, patches and comments across project boundaries. It even interacts with external bug trackers, such as Bugzilla and Trac.

There's also the standard things that we've come to expect in a bug tracker: web, email and API interfaces, links between bugs and fixes, team-based delegation and more.
