It would be cool if the itch app could automatically set the "Now Playing" field in the Discord App based on the itch.io title field. Or is that already possible?
You would have to have this as an option, maybe some people don't want to have Robert Yang's spanking game as their status by accident, or other NSFW games, or they want to add games manually like Discord does it on Linux right now.
I think there is already a Steam integration in Discord, but I did not look at it in detail yet. I will ask the Discord people about this also.
