The form control for specifying which series is a project's development focus has the label "Development focus", and the caption "The 'trunk' series where development is focused".

That's not a useful explanation. If it really is "the 'trunk' series", why does Launchpad let you set it to a series other than "trunk"? And why does Launchpad need to know?

It turns out that changing the development focus (a) changes what "bzr branch lp:project-name" does, and (b) makes a bug report say "Tracked in <name of development series>" for the project-in-general if the bug is recorded as occurring in the development focus series in particular.

The caption should be reworded to explain what the development focus actually does.
