Weapons, Missiles and Beams : There was a bug in the calculation of groups of elements (also it didn't scale very well (leading to lag)). Both of these issues are already taken care of.
Bug using catalog : Didn't notice that bug yet. Thanks, I'm going to fix that.
Doors and Energy Fields : I already planned doors as the last new block feature for the space stations update. I like the energy field idea. I actually originally planed the gravity block to activate for an area rather than having to activate it. My concept was (and still is) to extend the gravity module to be able to make a portal (out of at least 4 blocks), which would give gravity to any object passiing through it (even ships).
Docking Module : The restrictions around the axis are already implemented. I like the idea of being able to restrict the axis even more. Maybe I'll make it so the Docking module can be activaed, which brings up a dialog that lets you customize the max and min angle of each axis yourself (of course limited).
As always, thank you for the suggestions and bug reports. keep em coming
cheers,
