Thanks for this soft that is verry useful !
Something verry interesting would be to get the possibility to add new options for sharing news.
Currently, I use Push to Kindle (to create epub files from any URL) ; tomorrow, perhaps that I will use something else and I understand that you may have to restrict to the common tools.
So, my suggestion would be to get the possibility to customize sharing options, letting users writing their own rules from the news URL.
(Sorry for my english.)
