As someone who is able to modify lua I'm always very happy if game mechanics and user interface is opened up to modification by players. I've been very disappointed when I couldn't find either the ship editor nor the user interface when you are flying around anywhere in the opened lua sources. Many parts of the UI give the impression to just be added to have something to use and then be left as 'good enough'. It is tedious to access ships or stations via 'F' and even worse interface design to have to press shift to free the mouse and then to move it up right to access the trade module. How i'd wish to bind that to a hotkey.
To make that more logical, I'd call it 'grouping', as do many other 3d model editors. A grouping of blocks can then be used in the same way as a block itself, i.e. rotate, resize, fit to somewhere and so on. After adding a template of blocks (hm, isn't that just like a grouping there?) you only need to add said template instead of recreating a good curved grouping of blocks. Deliver the best templates with future versions of the game and voila, your wish was fulfilled. ;)
