My idea is to add a feature where users can upload a photo and then use a marker to draw on it. Doesn't need to be super fancy, even if it is one red marker option that would be helpful.
My use case example: We are an event company and want to have a user at the event location take a picture of the space, then use a marker on the image to draw, roughly, where a new banner will go. Then this will be saved and can be sent to the event team.
I think this would probably have functionality in other areas too. Potentially site inspection where you need to circle damage for example.
