A serious logos suggestion: integrated microphone or "hey logos" feature. In listening to books on the road I would LOVE to be able to say, "Hey logos, highlight that last sentence."
There's already the capability of microphone text transcription with any standard phone, but having voice-run UI commands Alexa/Google/Siri style would be a game changer. Voice commands in the pipeline, anyone? Any chance of success? Too expensive to ever implement?
