Since LR on desktop has so much empty real estate at the top, I am hoping to have the ability to create a row shortcut icons of my choosing to place there, especially for repeating and frequently used functions. For instance, if I want to create multiple Linear Gradients, currently I have to click "Create New Mask" EVERY time. I would like just a single button that I can set that goes to LG, or RG, etc. I would also make one for the Region Tone Curve, or one of the RGB curves, or the Point Color, etc. The amount of time it would save on scrolling+clicking would be astronomical!
