This is a great update... Undo Redo in the plugin is worth the price of entry alone!

I haven't used Editor V2 enough to form an opinion to comment but,
agreed, that the "Undo-Redo" is a great thing in a plug-in but don't forget the "Paste". Use it for dropping beats while in play, much more musically intuitive than boringly counting bars and beats and paste at numerical position:/ then rewind and finally listen. And then do the same again for the next.. phu! No just Copy on the go and drop it into the moving arrangement and alter the pitch the next loop. It's actually fun and THEN it gets used. The fun-factor in music is important for good results.

In Melodyne Studio (that wonderful futuristic software) I have "Paste" assigned to a single-key, I copy blobs from track 1, select next track and just drop samples in through-out the song, very musical. I have single-key short-cuts for toggling arrangement and editor-window while on the go and of course single key short-cuts for toggling "play arrangement-play visible" to edit (even on the go). Also have single key short-cuts for all the tools: just simple A-S-D-F-G and so on, very efficient!! Actually I have left-hand short-cuts for everything... The mouse do selections & modulations. So in Studio I am 'never' up in the Bar-ruler except to set a loop. just hands on blobs in the arrangement-window. It's like an instrument really. Actually 75% of the Editor wish-list is already implemented in Studio, it's true! Handling Stereo, sharp outlined blobs instead of intended notes rectangles, MIDI-in and much more.

But this post is on Editor 2. The time-handling tools are good for shaping symphonic instruments, synth-pads with to slow attack and of course to alter vocals. I still miss a fade-function though and still use the old "cut the last bit-drag amplitude down-make fade-out with transition from the main blob". It works, but it's not optimal. I am going to ask for "always show pitch-error cents during play" for the high-lighted blob that the play-line passes over regardless of tool, it would save lots of time for monitoring and surely there is a little space for it? But that's a topic for the wish-list, my second home, but I do pay rent to be there!

"Wrong is right"
So don't set reasonable limits to functions, let the user use it.

Yeah, I am totally with you on the key commands. I too have most used commands mapped for extensive, time intensive vocal arrangement repair work.
Even just being able to select the tools in Editor 2 would be great... In fact, just before I received notification of your post, I was rifling through the manual to see if they had been addressed with key commands.
