1. Local Adjustments: Though the editing through the entire image are wonderful, but I still there will have the local editing feature in the future. That'll be a great improvement through the image editing
2. Mask Tool: I like the mask tool in the Snapseed very much, it was very useful for editing some creative images and I pretty want this feature could be added in.
3. Double Exposure: Again, still very useful on creativity.
4. Add Texts & Images on the image: Though it isn't a necessary tool for professional image editing, it will be a feature that will my life easier. I could just complete the whole process rather than switching through hundreds of apps.
5. Bokeh Effects: It was a function a like when I editing photo, still hope that you can add it in, the more the merrier
6. Image Cutting Improvements: The image cutting is pretty powerful on it but I hope that we can crop the pictures into some specific shapes like circles, triangles, or stars. And I do find out is that when I want to custom the image's ratio, I can only input the INTEGERS rather than the decimals. The custom ratio cutting made me like your app very much, so it will very sweet if this could be improved.
Wish your apps will be greater and greater till the best
