They forgot default button on each panel : for example, when I make changes in the color mixer and after continuing to work the image I see the colors should go back to default I have to select colors one by one and set to zero again. Also the crop tool is horrible: if you make a selection for crop but want to remove (instead of resizing it) and select again you mustgo to the menu and 'reset crop' and then search again in a list for the aspect because it really resets the crop; yesterday I just had to click outside the image to reset crop but not the settings for new crop aspect.
I believe they forgot to include the loupe also - I have to press a key in the keyboard to open the loupe but sometimes , until yesterday, I prefered to click on the loupe button. But I am still searching for the loupe. The new layout is weird and I really don't understand why these confusing changes.
