As far as i know there isn't a feature for this in Pokertracker yet, but correct me if im wrong.
It would be cool if you could create color coding or/and custom notetracker comments based on different dependencies/variables. Much like the custom filter feature in Reports. The use for this would be to more quickly identify leaks on opponents during play.
A very simple example:
Player X continuation bets 100% of the time but does not follow up on turn and river.
Feature request #1 colorcoding example
If cbet_turn is less than 10% lower than Cbet_flop then cbet_turn_color is red.
If cbet_turn is between 10-20% lower than cbet_flop then cbet_turn_color is yellow.
If cbet_turn is more than 20% lower than cbet_flop then cbet_turn_color is green.
Feature request #2 Notetracker example
Basically the same feature request as above, but instead of color coding being the output you may define custom messages for notetracker instead.
So let's say that the cbet_turn was 80% lower than cbet_flop, and the cbet_flop was 100% the player would only follow up 20% of the time on the turn. That would be a big leak and you might want Notetracker to make a special note for that.
