a small thing.. sometime i need to use this workflow: without touching my keyboard, copy a hex color number from a reference > paste it to hex color textbox > click OK.
i know i should press enter after input the hex code, but imho it will be more convenient if the Ok button do what textbox key enter event do when clicked.
It’s not only about the HEX color, it’s like that with every value, but we are aware of it, and a fix is in the making. 
Fixed, will be released soon.
thats great, thanks!
