I’d love to find a way to quickly prioritize stories in the backlog- tab to highlight the next story, “5” to rate it as medium priority, tab to move to the next one… I’d also love to find a way to see recent comments on stories directed toward me- and then a way to respond. I can search through all Jira tickets that @-mention me, but there doesn’t seem to be a way to clear the comment from my list as soon as I reply.
