Hi Vlado,
Thanks for the suggestion. On iOS, there is already the ability to reorder adjustments (in the menu in the upper left corner of Edit). You cannot totally hide adjustments, but you can collapse them by tapping on the titles.
Mac doesn’t have the reorder feature, but it’s planned for 3.0. I also hope to add a hide feature as well, but am not sure yet.
By hybrid app, if you mean using Apple’s Marzipan technology, then no. However, RAW Power on iOS and Mac share a lot of code.
