I've been playing pretty regularly for a couple of years now and have recently decided to actively study, so I've been using XG2 to review my games. After each match I go over all of my errors/blunders and try to figure out why they're wrong, but it feels like there's probably a lot more I could be doing with this software.

Any awesome features I might not know about? In particular, anything that would teach me how to figure out rough win%/gammon% on the fly in a given position would be tremendous.

FWIW I play mostly 7-point matches and my PR usually lands somewhere between 7 and 9, so a lot of the best features may still be over my head, but any tips would be appreciated.

What I usually do when reviewing my matches is I open a new instance of the software, and when I see an error, I copy and paste it into the other instance. Then change a single feature of position and see how the bot's verdict changes. You can also play with the match score (if matches are what you're analyzing). It helps learning which features are most important in given situations much quicker.
