[development] Usability issues

[Erik Stielstra]

In order to collect all usability issues in one queue and to focus the  
usability efforts, all core usability issues have been re-organized.
During the documentation sprint in Szeged last sunday, the active User  
experience issues have been moved to the Usability component of the  
Drupal project issue queue. And further 'Usability' titled issues from  
other core components have been moved to the Usability component too.

Please file you new core usability issues in the Drupal project issue  
queue under the Usability component

Regards,
Erik Stielstra
