We need the exact Same thing since years for the ios photo app. It is really annoying that if you are looking at photos from the ios device, you can upload these to dropbox, synology, skype, whatsapp, but not add them to filr. Please finally fix this, as you did it with the mail app. This would really ease our way and ability to use filr. Thank you, Holger
Coincidentally - we have started working on this :)
Won't make it to the 3.4.3 version which will be released in a week.
But will be the release post that.
Let know if you want to beta test it once its ready.
