Hi everyone!
I guess command line in Rhino one of that thing which make us to fall in love with this software from the first opening 
Because it is fast, very fast! But sometimes, especially at repeating of the same operations it makes workflow slowing down. So i have some idea how to make this function little more convenient.
What if you make the command line right below the mouse cursor, with number line-sliders, something like at screenshot below:
Interesting to hear anyone’s opinion.
