This may have been suggested already and I'll certainly be embarrassed if it's already a feature and I'm blind as a bat but I digress. The current method of rotation is fine for most people but my hands are not that stable. I cannot move and rotate objects in a way that satisfies me by click and dragging with the mouse. I would love to see a GUI that allows me to rotate and move objects numerically. If I want an object rotated 63.762 degrees along the X-axis then I could easily do so by typing that number into a nifty little GUI. I've played games in the past that had this functionality and it was wonderful. If it could be added then this game... will probably get me fired from my job due to how much of my time it will be taking up at that point lol. Anyways, that's about it for my suggestion.
