I made a free tool for memorizing and training custom preflop ranges. There is a classic hand trainer which you can use for any spot as well as a chart trainer for looking at ranges on the aggregate. Additionally, there is a tool for reporting which lets you see exactly what preflop mistakes you are making in the trainer. It is completely free (Windows, Mac, and Linux) and I think would be useful for beginners trying to grasp their preflop ranges.
Sure! However, I believe the hand trainer already has a call function, so you can use that as your limping value if that makes sense. Right now I do only have it so you raise one size. Are you saying to add another raising button to provide an all-in raise?
Yeah, right now I am not sure why folks are having window sizing issues. I don't experience these on my computer and so I am not sure the exact issue. If anyone who is having window sizing issues has a chance to maybe contribute to the Github I'd be happy to look at it.
