Batch Operation to multiple issues

You could manage all your tracked issues in a popup window. To open it you can click the menu item "View all tracked issues" from top menu or the link "x of y" from the right panel.

In either way it will display a popup window as below, you could do the same operations as right panel to each issue by clicking the toggle button or the dropdown in the action column of the list.

But the most useful function here is doing batch operation to multiple issues one time.
