We used to simply hover over the assignee name and a little pencil appears and you just click on it and a drop down menu appears so you can select what user you want to assign the issue to. Now for some reason, when you hover over the assignee name, no pencil appears and only 1 link appears under 'Assign to me'. Of course there is also the 'Assign' button or tab that clicking on it will open a modal window where you can select what user you want to assign the issue to.
I just need to somehow allow the hover over assignee feature back because no body really likes to go to the 'Assign button' and change it from there.
Hope my concern is clear.
I think the resolution to this would be in the permissions.'Assignable users' or ' Assign Issues' Global Issue permissions. But i'm not sure
