I feel the hand range reduction tool is not practical.
It's hard to select everything you want.
For example, if I want to select nothing - Ahigh hands, I can't.
Also it treats different pairs in the same group, and maybe I don't want to.
Also you should be able to remove Ahigh+FD for example.
The way you could improve it is by letting the players select the combos they want in the grid, like add/remove combos by clicking on them and create groups.
Say, group 1, group 2..group n, with different colors. And then I put my Top pair or better on group 1, flush draws on group 2 ...etc whatever I want, do you catch the idea?
This way we could easily see #combos ahead, #combos behind, #air combos...etc in a more practical way.
Thank you.
