When you call "return" in Python, the function terminates, so this will
exit the loop after the first iteration.

Views don't simply iterate automatically -- if you want to repeat some
elements in a loop, you have to write an explicit loop. Instead, maybe
something like:
def important():
[snip]
return dict(packages=[package.name for package in cache.packages if
package.essential])
View:
<ul>
{{for package in packages:}}
<li>{{=package}}</li>
{{pass}}
</ul>
or even easier:
{{=UL(packages)}}
Note, if you pass a list to the UL() helper, it automatically converts its
elements to LI's.
