The current iteration of the NOW buttons for Departure and Arrival on the Manifest Legs page are completely inert, they have zero indication that they have been pressed/activated unless you take the time to watch the (unnecessarily tiny) date/time group change.
My helicopter EMS company has a LOT of older pilots who now need reading glasses, and it would be a LOT easier to see if those buttons have actually been pressed if they did SOMETHING. When pressed they should DO something: change color, change size, change shape, haptic feedback, all of the above, anything except the nothing at all that they do now.
