It does look very nice, but as with all fancy debugger features I wonder if I'd spend more of my life debugging the debugger when it doesn't debug than it'd save me.

I also think that while a debugger is a great and useful tool, being able to debug without one is a requirement, because sometimes you don't have one (or it stopped working properly - see recent Android Studio releases) and if one can't do it just using logs one is really stuck. So it's worth getting practice at that.
