I want a quick filter on the rapid board which allows me to filter by an assignee of my choice. Currently there is only a quick filter for issues assigned to the current user. As a project manager or lead, it is useful to be able to easily see what work is assigned to who.
Instead of a simple button, the user would be presented with a dropdown list or a text field.
Swimlanes could be used for this, but I want to use swimlanes for other purposes while filtering by assignee.
More generally, it would be useful to be able to define quick filters with a variable parameter. That would solve this case and probably others.
