Get more drupal.org project usage information Choosing a Drupal module has become an art-form.  Deciding if the module is active, used frequently, growing in usage, etc. is important.

I'm a site builder.  https://drupal.org/project/usage has lot's of good information but interested in levaring the view.  What kind of URL arguments are supported?  I know that:
?sort=asc will work, but can I filter by category, change time range or make a more sophisticated query?  I can add https://drupal.org/project/usage/webform and get more granular on a project basis but would like more control and to understand the URL arguments supported.

I didn't find any Project documents that were relevant.
The usage page comes from project_usage_overview(); it's not a View.  The only parameters are those provided by Drupal's tablesort API, "sort" and "order".

?sort=asc you've already discovered, and the other parameter changes the sort column (?order=Project would sort by project name).
