Lets you search for JIRA tickets, open them, transition them thru different states, comment on them, rank them up or down, start or stop watching them or change who is assigned to a ticket. Also, notifications for assignments, mentions and watched tickets.
I can search and create issues, but watch/add comment/add label does not seem to work. Example:
but when I check the issue log no changes have been done / watchers have not been updated
