Further evaluation needed.
Bugtracking API needs to provide a mechanism for grouping tasks. Dashboard needs to know how to group and by what to group (e.g. provide a set of attributes for grouping).
Enable grouping for categories? If yes, how to handle different grouping attributes from different repositories within one category.

We have to decide if we will use original specification for grouping (and resolve pending issues) or if we design more lightweight ordering mechanism.
Original spec: http://wiki.netbeans.org/TaskDashboardDesignSpec
We decided to use just editable sorting - no grouping implemented.
