With Capture One Pro 8.1 Phase One introduced the possibility to show important tool options via right mouse click. This is a nice little feature I am using on a regular basis. When you select the crop tool for instance you can right click to display important crop tool options such as aspect ratio or units. This makes working with tools very easy and fast. Love that.
Would you like to see some more quick C1 tips? You know, I did such things in my "old life" :-)
