A percentage of income still isn't equitable though.
If you're destitute a week's income means you starve.
If you're a millionnaire a week's income stings bit doesn't affect much.
If you're a billionnaire there is a good chance you don't technically have an income, and if you do you can lose half of your wealth without feeling it.
Props for finally doing it, but a modding API was promised more than 10 years ago!
