ZappoManAdded new feature to MenuRow to allow custom callback for State Note: there's some bug in the menu render code that doesn't like state strings that are longer than 4 characters + NULL. So, the current code will clip any state string that is longer than 4 characters. We need to look into this 5 character limit. It's a bug.e921d0613 years agoHistory
