Lots of promise - a couple requests – BLACK - B&W Film Emulator Review

I've used this app for quite a while so I finally paid for the upgrade to use the fade, curves, and vignette. The app renders some unique and pleasant results for B/W emulation with a few small caveats... In the next update it would be great to see: - A/B control of "original photo to filtered photo" - a press and hold on the photo within the app would be preferred. - MORE FILM EMULATIONS PLEASE!!! The existing filters are great but they're limited. Would nice to have more options. - Fade works great, but Curves and Vignette in particular need a little attention to be more user friendly and useful. i.e. When using vignette - it's not engaged until you tap on the screen and move it around a little. This makes no sense. In addition the fine controls for vignette are clumsy and make rendering a proper vignette a pain in the butt. Would also like to see a center focus feature to accompany vignette to help illuminate the center of the photo. Lastly, curves is pretty much fine but a "hide feature would be great so that the results of your adjustments could be more easily seen & it would also be nice to have a clear all feature to remove all nodes. - Last request would be to have a feature that allows the easy removal of a vignette or fade with the tap of a button, like clear or something if you change your mind. Awesome app overall just needs a little fine tuning.
