I just installed Open Atrium 2.0 and noticed, as many people have, that the Issue Tracker functionality is not included. I understand why they didn't want to include it in version 2: to make way for a better solution that fits in with Drupal Core.
However, this functionality is pretty killer for what I use Open Atrium for.
So, other than https://drupal.org/project/oa_worktracker, are there other alternatives to implementing issue tracking within Open Atrium. I guess I'm unaware of a standard issue tracker for D7.
