It’s not always clear what category settings have been applied for a particular category. And as it’s a key part of how category-based budget reporting is performed, this setting is now front-and-center on the Categories page. It’ll show as either “Income”, “Expense” or “Expense and Income” depending on the category type settings which are applied.
In addition, the category type will now automatically change to the correct type, if you edit the only budget in the category to be a different type. So if you accidentally create your “Wages” budget to be an expense budget at first, editing that budget to be an income will have the category type change to income.
