Hi sandykoufax, it could help me if I understood why the right click to cancel was useful. If you start the circle command for example, how is it that you then don't want to draw a circle anymore? I mean is it because you meant to actually run some other command and you were in the circle command by mistake? Or is it something else?

You can also cancel the circle command by pushing the Cancel button, using the Esc key or just starting a new command which will cancel the current one.

The main reason for the switch was that now the Open and Import commands will show some UI with a cancel button on it, and right clicking in a viewport would then cancel the file load which doesn't seem good to do.
