Edit Redmine status transitions as a flow chart instead of a checkbox grid, over exactly the same rules.
Documented for version 1.2.1 · Verified against 3bbd906
Your status transitions, drawn as a diagram you can edit. The checkbox grid is precise and, past about a dozen statuses, unreadable — you cannot see that a status is a dead end, or that nobody can reach it, by scanning ticks. The diagram answers that at a glance and lets you fix it in place. It is a view over Redmine's own workflow rules: there is no second store, no sync step, and nothing to reconcile.
