Aye it's a bit of a pain now but as has been said it EA before the first big patch so lots of tweaking is yet to come. For example 1 thing I'd love to see in the future would be making it so walls create a barrier of "non spawning", basically make it so if you create a fully enclosed area of wall anything on the inside wall of it is an area enemies won't spawn.

It'd also be cool honestly to have something that counts as a workbench for building as right now I don't find it a massive issue as you need workbenches covering the entire area of your base so you can build and repair inside it.
