Show automation lane of last touched parameter

I totally agree.
but I have workaround that works nice for me:
I press play, then i press W button (its for automation wright mode on) then I tweak parameter, then I press W button again so wright mode turned off and then I press ctrl-z to undo changes on automation lane.
option to automatically show automation lane that being wright on you can find in prefs of automation panel. heres screenshot of how you can find it http://joxi.net/L219EwwCR8ldy2
