I bought the Osmo to, between other situations, capture me playng guitar while recording in my studio.
It is necessary to capture the video in a larger range than the distance of an arm, onde I need that the guitar fits inside the image.
The lighting cannot be very intense, and so if I set the autofocus mode to AFC it keeps pumping, and when I set to AFS, I can't reach the screen to tap it and focus, once I must remain at almost 1,5 meters (5 feet). If I get closer to tap, the focus will be set to a shorter distance, and when I walk back to the recording point, I get out of focus

I've seen many threads asking for a manual focus interface
When will you listen to your customers wish?

unfortunately the AFC often produces undesired effects... I agree with that
