Mint does not natively let you remove any default categories or sub-categories, although you are free to add and remove any custom sub-categories you want. Since many built-in categories may not be applicable to your financial setup, this creates unnecessary clutter when organizing your transactions. If you don’t own a business or do not have kids, for example, there is no logical need to have those options always show up in a list.
This addon gives you control over these built-in categories. You can hide any sub-categories and even top-level categories that you do not wish to see.
Does not contain any tracking, analytics, ads, etc. It’s free and open source, so feel free to post any problems or feature requests on the GitHub page.
