I would like to see an ingame upload function.

At this moment i make many snapshots but mostly forget to upload them.
If there was an ingame upload function (button ) i wouldn't forget it

Unforatunately, that isn't possible. There is no in-game API that would allow for such a feature.

What you might want to look at though, is UniUploader. You can read more about it in the General Forum. It's easy to use and you can even have it set up to always upload when new data is detected!
