Code sprint is always fun. It's gives you great opportunity to meet fellow civi folks, collaborate and implement kool stuff :). Last few days has been very interesting. Besides some great meals we also managed to get some work done. ( If you still don't know, food is the most important part of CiviCRM Sprints )
First we shortlisted features / improvements that we want to accomplish during this sprint. Complete list is available at: http://wiki.civicrm.org/confluence/display/CRM/UI+specific+tasks
We started the sprint by converting getContactList(), function that is used in quicksearch into api v3. This will allow developers to build quicksearch like interface ( autocomplete ) on any civicrm forms using jquery or smarty. For eg: "Current Employer" field in profile can be converted into quicksearch autocomplete field using this api.
