Playtime Tracker

I'm only speaking about JAVA addition in this because I know nothing about bedrock, but if this also applies to it then it works for both. I'm pretty sure everyone wants a playtime tracker added. I know that there's a setting in Statistics that shows how long you've played on a specific world, but a lot of people (like myself) have played on a lot of different devices and they don't have a way to track all of the worlds they've had. I'm sure there's some way to link your playtime to your ID. That data has to be somewhere out there, it's just a matter of organizing it. Considering how many people talk about there being a tracker for their Minecraft accounts I'm honestly surprised it wasn't integrated YEARS ago.
