I was hoping someone with a Logitech Harmony Elite could answer a couple of questions for me about the dedicated smart home buttons at the bottom of the remote.

1. Are these buttons activity independent? I.e. Do you need to program the desired functions of these buttons on a per activity basis, like the normal buttons - or just once and they perform the same functions regardless of what activity you are in?

2. Despite the pictures on the buttons (left ones show lights, right ones show power points), can I assign lighting modes to all 4 buttons?

3. For anyone who has upgraded from the Harmony Ultimate, is it worth the upgrade to the Elite if you want to use it for controlling the lighting. I.e. do you find the dedicated smart home buttons to be very advantageous over having to use the touchscreen for these functions?

Thanks
