Alpha V3.7 has now been uploaded to steam. The focus of this update was on adding additional ease to the customization process of the ship. Overall ship building should now be a lot smoother. Take a look at the changelist notes for a more in depth look.
A heavily requested feature was the ability to click and move ship objects around with ease. While in the build menu you can now select an object and place it on an available location. This should greatly aid in misplacing objects.
Along with item placement a big request in room construction was the desire to increase and decrease room sizes with ease instead of completely removing a room and placing it down. While in the build menu you can now use room increase or decrease options when the available.
