They are and we are really sorry about that, we just can't physically get them any better. The reason is because we are currently getting the Hab Block done externally (something we don't really want to do) but after 25k everything changes. As this is popping up quite a bit we are going to see if we can do anything about it at all, so watch this space.
Yes I think there is. We are currently looking into unlocking parts of the Hab Block bundles so you can order them through the pledge manager as additional Hab Block parts, eg Additional Roof's, Walkways, Armour etc
