I am using the Pushover plugin and I like it very much. Would it be possible to add the feature to push a picture at regular intervals, as long as the print is going on? With intervals to be chosen? So I would get a pushover message with a picture of my print every x minutes as long as the print is not finished? That would be great!
Since I am using Pushover mainly for my home automation, I am happy that I can use the same tool for OctoPrint, too. I don't want to start using a 2nd similar App only to be able to use the requested feature. Maybe if I find the time I could look into the source of the plugins you mentioned and try to copy this function into the pushover plugin. But I am no Perl programmer, really.
