I am not trying to be a naysayer but I want to urge everyone to timber their expectations. In a corporate structure like Niantic there are many levels that an idea will have to travel through before you can even be considered for implementation. The idea will have to go through the development team, the programmers, legal department, and if it to gets approved it will take a great deal of time before the programming is done, tested, and the idea gets implemented.
My personal assessment is that it could take upwards of a year before anything would happen. As there are many amazing ideas floating around I do hope that I had it picks up many of them, but I do want to make you aware of the process.
