I love the convenience of the Notification Drawer in Confluence. I can quickly see any updates before I get an email notification about them. I would love to have this feature available in Jira.
Since I am on the engineering team, I am in Jira about 90% of the time. I always have several tabs open with differnt agile boards and bug tickets. It would be awesome to have it available in the area that I frequent the most. It would also allow us to decrease the amount of email notifications that are sent out.
