Improve issue board configuration experience
Since 10.2, issue boards can be configured so that the issues it displays are scoped to a set of parameters (assignees, milestone, labels, weight)
The current implementation allows the user to set this configuration in a modal. On subsequent visits, the same modal has to be accessed to view the parameters of the configuration. This is problematic because when a user lands on a board they are not automatically informed of its scope, which is an important element to understand the set of issues being displayed.
Another problem is that once a certain parameter has been applied to the board's configuration, it's not possible to add a temporary filter with a different value. For example, if a board is permanently scoped to milestone:%10.3, it's not possible to temporarily filter the board to milestone:%10.2. The user is required to set up an identical board without a permanent configuration before they can apply such a filter.
