Corner Markers - Have a marker within the app so that you can 'enable' specific corners to detect the transfer of devices for the flow functionality. Example: Only bottom right corner, have a marker so that it can only detect when it reaches that threshold. Or another, enable all three markers, i.e top, center, bottom so that you can have it additionally sensitive to any part of that one area of screen. I think this would be super valuable with the flow functionality as it could help with knowing where to go for the end user. On top of that, it would be nice to have a chime/queue to notify the end user when a transfer occurs in the system options. For example a small bar appearing.
