Why not allow the blueprint camera to work on any structure or boat? Whether it's inside the protective barrier or not? IDK how hard it would be to implement but I can't think of a reason not to.
Also, you might consider making the protective barrier something that you can move. You would still get only one, but you could move it to new builds. This would actually add an interesting aspect to PvP because moving your barrier would leave the existing building vulnerable. For example, you use your barrier to build a main base at the heart of your yland. Next, you want to build a tower by your dock for defense. You could move your protective barrier to the new build location, leaving your main base vulnerable. Reward but not without risk. I believe this would add a whole new layer of complexity to PvP while making building easier and more adaptive.
An auto-sort button for inventory please.
That's all, keep up the good work
