This feature is very buggy for me and is not applying the correct colors.
I have used this feature many times before in HEM2 so I'm confident I have set it up correctly.
Settings I'm using:
I deleted the pre-existing definitions and created my own new ones.
The definitions I created were very simple and based only on "VPIP (compiled)"
I selected Pot limit omaha hands only.
After executing "Color Code Notes based on active definitions" , the color were applied but there were many players who had the wrong colors applied.
Also, there were many instances of me selecting FILE -> SAVE for each definition, and the saved changes being lost!
