Agreed. I also wouldn't mind a lot less verbosity when giving it a command rather than a query. Turn off the lights, or set a timer for 15 minutes could probably be confirmed with an "Ok" or even just a pleasant chirp/beep sound. "Ok Turning 15 light off" "You got it, timer set for 15 minutes" is unnecessary.
The chime feature is enableable, and it's pretty tolerant on input too. These days I just say "Alexa bedroom off" and Alexa does the right thing. Getting rid of the cue phrase would be nice though. That is, if intonation or volume or directionality of my voice could help it determine when I'm giving a command vs random conversation.
