It would be great to include an advanced search for Sunsama issues: being able to filter on not just the channel but date on which the issue was created, whether it is connected to a GitHub/Jira ticket, what its status on the other system is, and so on, would be quite powerful to help clean up Sunsama when too many issues have piled up (if you've been sick, say). This could form the basis of more advanced search options (e.g. cleaning up duplicate issues) and smart lists.
