There already are workarounds for this but I thought I'd pop up a suggestion for a QoL update as it might not be too difficult to implement in the future codewise. Cameras don't have a feature right now where you can prove date and time information without additional work.
I thought it might be beneficial for the PhotoPlus (not FunCam) to have a setting for date and time to be included in the printed picture, or maybe even a newer, more expensive model of camera with this feature built in.
I also understand however this might make photos a lot more incriminating when it comes to evidence, so there's potential for discussion there.
