Some providers have identifiers for each issue (GitHub issue number, Jira ABC-123 task identifier, etc). I would like to be able to search by those identifiers (e.g. if I search for "54", it should pull up GitHub issue 54 as well as issue 545, ABC-454 and so on). This is mostly to help me find a task from outside Sunsama (maybe someone messaged me a GitHub PR I needed to review and I want to see if it's already in Sunsama, maybe I left a Jira issue page open in my browser as a reminder that it needs to be fixed urgently), but could also be helpful in providing a warning if I try to add the same task multiple times.
