Yes, it's all good. Mirza is my first name. About the terminology: "Command Line" refers to the command line window, which is located on the bottom. But when DYN (Dynamic input) is enabled on the status bar, then all user's inputs are directed to the "Dynamic input box" which is marked as 3 on the image that you provided. I prefer to call 1 and 2 just as "Length/Angle" edit boxes. Of course, if user clicks somewhere inside the Command Window and starts typing, then "Dynamic input" will not be active, and everything typed will be displayed in the command window.
I forgot to say that I fixed problem about attaching images to forum posts!
