I recently played Tim 2, and found the whole "Right click to clone object" really useful. Is it planned to be integrated to this game? Playing with a mouse, right clicking on an object just placed is faster than going to the bin on the right. I know it's a small usability tweak, but one which I've found myself try several times to use only to remember it isn't in there.
And keyboard shortcuts. Are there shortcuts to start/stop/fast forward? I found the pan function when pushing space to try to start the contraption and noticed the hand cursor.
