After really getting into using the iPad for editing over the last week, I have come up with a few things that I think would really help improve the speed of general workflow:
1) One powerful tool in the tutorial videos takes a number of steps, and are thus kind of cumbersome - it's creating the non-destructive dodge/burn layer. You have to create a new pixel layer, fill it to 50%, set the blend mode to overlay, then finally you can dodge/burn on that layer. So why not have another option in the "+" menu for layers, where instead of adding a pixel layer you can "add neutral overlay" which does all that in one step. Honestly it's what I thought "Add Fill Layer" would do, I can't figure out what that actually does though.
2) I have a small set of Adjustments/Filters that I use regularly. I know you can change between sections like Noise/Colors/Blurs instead of all filters, but for both Filters and Adjustments it would be great to have a set that was "most used" and give you 6-10 of your most frequently used options.
3) It's great that I can copy groups of adjustments into another images, quickly change the mask under the group, and get an effect I like applied to a part of the image quickly... but I end up doing that with a few different kinds of adjustments, so it would be nice to be able to create some kind of palette with groups of adjustments/filters already set to specific values that I can bring into an image. One practical example is a set of adjustments for skin smoothing, I like to use a combination of Bilateral Blur & Diffuse glow at very low opacities to get close to the skin smoothing I used to get from the Nik ColorEFX 4 filters.
Thanks for a great tool, as a data point for you I get all my files in and out through iCloud (which has been working really well so far).
