There needs to be an option in the hud to tag the current hand. While multitabling, you sometimes forget to tag the previous hand as your focus shifts to other tables. Or you just forget which table it was on. But while playing a hand, if you face a tough spot, you can tag it then and there.
To make space, I think the option to “tag previous 3 hands” can be removed. I’m not sure if anyone actually uses it. Do people really face the same spot in 3 consecutive hands?
