You've ruined Lightroom mobile for iPhone! PLEASE fix it by putting the old version back? The sliders are covering a third of the photo! What a horrible GUI! Even The Lightroom Queen agrees (you ignore her at your peril)!
I think horrible is a quite harsh... but I would have to agree that a lot of the GUI changes seem to get in the way. If you are editing a vertical crop photo a lot of the image is obstructed by the controls. I like how it disappears when adjusting.
The toolbar could be broken into more categories. Also a lot of controls are hidden, it took me a while to find my tone curve, but I did like GUI of the tone curve tool once i found it. The spit toning interface was difficult to select the saturation level I desired.
Can we ditch the presets tool, or hide it at the end, until you can make your own these don't seem very useful, I'm looking at you Sepia Tone and Cross Process #3.
