I would love to have input select somehow built in because that's the only thinng I now still need to use my TV remote for. All my video comes through the ATV, but I still use inputs for PS4 and Switch. But yeah, I don't see how that could work well. Maybe long-press the power button, it brings up an input select menu with 5 buttons or something where you use the trackpad/cursor buttons to select the input, then it translates that to the IR for the TV? I don't think it can pass that through the HDMI cable directly like power command.
