Hi, I noticed that the part system as it is now is somewhat cumbersome. You got like a dozen different cylinders with fuel in it, for example. It makes searching for the right barrel really annoying. Also in the aerodynamics section the different wing types are hard to differentiate. Another thing is that for example all the side-mounted fuel tanks are monoprop only. How about that: You cut down the number of those items that are very similar. So you got the short, the medium and the long barrel and make them scalable in diameter. So lets say you click the long fuel tank, a popup opens up, there you can select diameter and contents: Empty, Monoprop, Biprop, JetFuel Scalability works for almost every items. This also goes for rover wheels, adapters, stack modules etc. Furthermore, all the items that are unique (in size) like say the different modular girders or the wings will be available in many more sizes, thus multiplying the amount of possible playercreations. I for example like those swept wings very much, but they are only usable for rather small planes. Or I want to side-mount my favourite fuel somewhere, but they all are filled with monoprop. My system brings the following benefits: Making the part menu vastly more accessible and well-arranged. At the same time, increases the total amount of parts by a LOT. Limitations like wing size or fuel contents make stock-only players (like me) somewhat frustrated. Others will modify the parts or use modded ones, therefore even more obstructing their UI's. And about execution, its not really a big deal. For most items you wouldnt need to make "scalable items", but just rearrange the ones already existing into my system. The unique parts would require the scaling system. But even if they were done in the different sizes manually, it would not be too much work for a single person and would seriously pay off.
