I was a pro user of this app on my Android but I could not restore this app with the same email address used on my iPhone.
However, still, I would love to buy again if you consider adding few features from Snapseed such as Selective editing (based on a color point), Vignette, Ambience, Grain, Healing brush, GND (graduated netrual density) filter editing, etc.
Also, let me save the edited version by replacing the original photo, not saving a new copy (a settings toggle would be fine).
Thanks for making such a great app.
