Allow for multiple instances of the same window to be open simultaneously
Currently, only one window of a kind can be open but there is benefit of allowing more. For example, I switch between RGB and HSB colours constantly when working. Being able to have two color windows at the same time, one set to RGB and the other HSB, would save thousands of clicks.
I'm sure there are many more benefits to enabling this option.
