Please not. I think this is disturbing, since what you do is to move the 
mouse and to confirm it with a click. This is faster. It bugs me that it 
destroys the option to add additional options to the tools by just 
pressing the same button multiple times. That is very quick and 
intuitive. I would not like to trade it against a "press again to confirm".

That is the main difference. You speak about simple interaction for new 
users. But i speak about fast interaction once learned. Yes this is a 
compromise to make. Power users want the shortcut mechanisms as quick 
and powerfull as possible. Nothing is more powerfull then a direct 
shortcut or to press a button again to switch between different modes. 
As an experienced (well trained) user i find it very practical to 
confirm with the mouse, to switch options with the keyboard, and to 
cancel an action by mouse or ESC/Strg+Z/Strg+Y.

To the "newbies". Would they really like to confirm an action by 
pressing the shortcut twice? The most users i know start to press a 
mouse button to confirm something. That goes for many things. An if they 
did something wrong, the first thing they do is to press the undo 
buttons or shortcuts.

I have to say: Personally i don't like this change. Pressing RR was a 
very convenient way to switch the mode. :(
