Rather than more platforms, for me some additional features would be great?
The ability to upload an image to Facebook, Twitter and Whatsapp, for example.
Or the ability to dynamically set which image to upload to any platform (is this already technically possible? I have only just bought the plugin so haven't tested it yet. Something like ' "http://image.url/" + IMGVAR' ?)
This is all running very smoothly so far though, so thank you.
