It only makes sense to debate details on the dashboard powers when the rules are reasonably finalised. However, the v2.8 I've just uploaded has the ATTACK action too, which completes the core rules. There's a bit more to add at the start and finish, but the heart is there.
We are updating a set of core box dashboards and should have these ready by the end of the week. Depending on layout time. Hoping for the end of the week though. The rest should not be far behind that.
Dashboards are 135mm wide, and 90mm tall for all except titans (who are 100mm tall).
