It would be useful to be able to sort your task list by Tags. Projects I have been on have used Asana as a bug database and one of the tags has been severity/priority. Being able to sort by tags would root out lower priority tasks. This would also be useful to sort out different departments tags (art, code, etc) for larger projects to more quickly quantify the department’s status.
The workaround for this seems less than ideal. Creating dummy accounts to assign to that would be associated with certain tags or assigning to various due dates that are specific to tags (preferably well in the future).
