Speaking off offset command variations, one thing I would be very interested in: interactive Offset Through Point with the option to put in a fixed increment/step size. For example an input value of 10 would snap the offset distance to 10, 20, 30 and so on. It's something I need very frequently, but right now I still need to put in the fixed distance myself for each one. I guess it would be nice if there was a Repeat option with that as well, so you could do multiple offsets interactively (with or without the step size provided).
