Zachary It is not planned to add 1x1 mining laser.But there may be some bigger ones. The one that is already in mod should be just right for what it will be needed in future.
I was planning to add a shields that share same power source from main part. I even suggested that in some modding threat to use it that way to make a space ship wrapping shields. More shields are definitely going to be added with not only shape size and color diffrences.
Gatekeeper It will ... It definitely will go farhter.
