Would it be possible to add to the next version of SGP a post request with to a site of our choosing? I use pushover.net, which has an open API. Pushbullet and other systems also have open APIs which I think could be used with a notification service.
In my case, it’d be great to have a post request sent to my pushover account, sending a notification to my phone and watch. With pushover, you have an option of selecting the importance level. For an abort notification, I’d send it as an emergency that would require me to acknowledge the notification - very useful for when asleep!
