The problem is, I don't have a mouse with 5 buttons, and I doubt most people have one. Could these commands be added to the ones we can re-bind to the keys we want through the uikeys.txt file? Maybe we should also add default keyboard bindings for this useful function, such as pgUp and pgDown, I don't think they're being used for anything else.Space Build (shift + mouse5/mouse4)
Gives your line and/or box structure queues an amount of spacing between structures (default spacing starts at no space). Each click of the spacing expand button gives you an extra LLT-based size space in between each structure on all 4 dimentions. Similarly, each click of the spacing contract button removes that amount of space. You cannot remove spaces when structures are already placed with no spacing between them.
Thanks!
