the sealers working would be nice, more or less the people i play with would just love the space aspect of it being more fleshed out, im really interested in the Solar panels tho, i tend to setup large computer systems and the power drain can get a bit insane over time. In the past i ended up with 150-200 magmatic engines running and i would end up drainning the neather of lava or having to endlessly mess around with mystcraft to find a lava world and that would just end up lagging the server to death for everyone else.
