Currently, Kanban and Scrum boards have the feature to right click an issue and select the 'Add flag and comment' and 'Remove flag and add comment' functions that flags the issue as impediment and automatically adds the icon to the comments, or removes the impediment and automatically adds the icon to the comments, respectively (see screenshots attached).
This feature, however, is not available on the issue view screen. Inside the issue view screen, it is only possible to mark an issue as an impediment by manually checking the 'Flagged' field using the edit issue menu, and this does not automatically add the flag icon and comment to the issue as the board function does.
It would be useful if the same feature present in the boards was available inside the issue view screen, perhaps under the 'More' menu. This would speed up flagging and unflagging of issues, and since it is a feature already present in JIRA, it shouldn't be too difficult to make it available from inside the view screen.
