Allow programmable block to make HTTP/HTTPS web requests
It would be a nice feature to be able to write PB scripts that can send data to outside sources and request data from them.
For example, a script could send position updates to a custom API written by a script developer. Another script could read the position data from the API to plot a kind of star-map onto LCDs.
External API's could be used to handle more powerful computing, returning data directly to the game.
I'm sure other engineers could come up with many more uses for this.
